 NAME
      vtwm - Virtual Tab Window Manager for the X Window System

 SYNTAX
      vtwm [-d display] [-f initfile] [-m [options]] [-p] [-s] [-v]

 DESCRIPTION
      vtwm is a window manager for the X Window System.  It provides
      titlebars, shaped windows, several forms of icon management, user-
      defined macro functions, click-to-type and pointer-driven keyboard
      focus, and user-specified key and pointer button bindings.

      This program is usually started by the user's session manager or
      startup script.  When used from xdm(1) or xinit(1) without a session
      manager, vtwm is frequently executed in the foreground as the last
      client.  When run this way, exiting vtwm causes the session to be
      terminated (i.e., logged out).

      By default, application windows are surrounded by a "frame" with a
      titlebar at the top and a special border around the window.  The
      titlebar contains the window's name, a rectangle that is lit when the
      window is receiving keyboard input, and function boxes known as
      "titlebuttons" at the left and right edges of the titlebar.

      Pressing pointer Button1 (usually the left-most button unless it has
      been changed with xmodmap(1)) on a titlebutton will invoke the
      function associated with the button.  In the default interface,
      windows are iconified by clicking (pressing and then immediately
      releasing) the left titlebutton (which looks like a dot).  Conversely,
      windows are deiconified by clicking in the associated icon or entry in
      the icon manager (see the descriptions of the variable ShowIconManager
      and the function f.showiconmgr in the BINDINGS section).

      Windows are resized by pressing the right titlebutton (which resembles
      a group of nested squares), dragging the pointer over the edge that is
      to be moved, and releasing the pointer when the window is the desired
      size.  Similarly, windows are moved by pressing in the title or
      highlight region, dragging it to the new location, and then releasing
      when the window is in the desired position.  Just clicking in the
      title or highlight region raises the window without moving it.

      When new windows are created, vtwm will honor any size and location
      information requested by the user (usually through -geometry command
      line argument or X11 resources for the individual applications).
      Clicking pointer Button1 will position the window at the current
      position and give it the default size.  Pressing pointer Button2
      (usually the middle pointer button) and dragging the window will give
      the window its current position but allow the sides to be resized as
      described above.  Clicking pointer Button3 (usually the right pointer
      button) will give the window its current position but attempt to make
      it long enough to touch the bottom of the screen.

 VTWM(1)                           X11R4-6                           VTWM(1)

      The default behavior during these operations is to represent the
      window with an outline of the client window and its titlebar, lines
      crossing within the client window.  Alternatively, vtwm may be
      configured to draw the window completely, but it is not recommended
      unless yours is a fast system.

 THE VIRTUAL DESKTOP
      vtwm is based upon the twm(1) window manager, but adds extra
      functionality in the form of a virtual desktop.  The virtual desktop
      is an area larger than the physical screen. The real screen is
      considered to be a window onto portions of the virtual desktop showing
      whatever windows are present in that area of the desktop.   To help
      navigate around the desktop, vtwm creates a new window, of the name
      VTWM Desktop, which shows the entire desktop using a small scale.  In
      the Virtual Desktop window, all windows that exist are displayed and
      various options are provided to recognize the identity of the
      different windows (see the descriptions of the variables
      DesktopDisplayBackground, DesktopDisplayForeground,
      DesktopDisplayBorder and VirtualDesktopFont).

      To provide a consistent workspace, the option is provided of nailing
      windows onto the real screen.  When a window is nailed, it is
      considered stuck to the real screen no matter what part of the desktop
      is currently being displayed.

      Normally, a few standard utilities are nailed down: the icon manager,
      the desktop view, a load average chart, a clock, and a mail notifier.
      The f.nail (or its alias, f.stick) function can be used to change the
      nailed status of any window; see the BINDINGS section for details.

      The root window of the display is unchanged by this program and
      utilities such as xsetroot(1) will continue to work unmodified.

 OPTIONS
      vtwm accepts the following command line options:

      -d display     This option specifies the X server to use.

      -f initfile    This option specifies the name of the startup file to
                     use.  By default, vtwm will look in the user's home
                     directory for files named .vtwmrc.N, .vtwmrc, .twmrc.N,
                     or .twmrc (where 'N' is a screen number).  It also
                     looks for system-wide default files; see the
                     CUSTOMIZATION section below for details.

      -m [options]   This option causes vtwm to preprocess the startup file
                     using the m4(1) macro processor. The options will be
                     passed verbatim to m4 along with those symbols that
                     vtwm declares.  Note that options itself should be
                     quoted, to prevent unwanted processing that may occur
                     by the shell, etc.

                               Release 5.4.6b



      -p             This option indicates that vtwm should attempt to write
                     it's PID to $HOME/vtwm.pid on startup, and delete that
                     file on shutdown.  This file may be useful as a lock
                     file, or for determining the correct vtwm process for a
                     particular user.  If the file cannot be written on
                     startup, a bell will sound, but vtwm will continue.

      -s             This option indicates that only the default screen (as
                     specified by the -d option or by the DISPLAY
                     environment variable) should be managed.  By default,
                     vtwm will attempt to manage all screens on the display.

      -v             This option indicates that vtwm should print error
                     messages whenever an unexpected X Error event is
                     received.  This can be useful when debugging
                     applications but can be distracting in regular use.

 CUSTOMIZATION
      Much of vtwm's appearance and behavior can be controlled by providing
      a startup file in one of the following locations (searched in order
      for each screen being managed when vtwm begins):

      $HOME/.vtwmrc.screennumber
              The screennumber is a small positive number (e.g., 0, 1, etc.)
              representing the screen number (e.g., the last number in the
              DISPLAY environment variable host:displaynum.screennum) that
              would be used to contact that screen of the display.  This is
              intended for displays with multiple screens of differing
              visual types.

      $HOME/.vtwmrc
              This is the usual name for an individual user's startup file.

      $VTWMDIR/twm/system.vtwmrc
              If neither of the preceding files are found, vtwm will look in
              this file for a default configuration.  Note that the variable
              is defined only in the Makefile, and is often set and tailored
              by the site administrator to provide convenient menus or
              familiar bindings for novice users.

      $HOME/.twmrc.screennumber

      $HOME/.twmrc

      $VTWMDIR/twm/system.twmrc
              When none of the .vtwmrc files can be found, vtwm reverts to
              acting like twm(1), and searches for these three .twmrc
              variants.  Note that the variable is defined only in the
              Makefile.





                                    - 3 -      Formatted:  December 22, 2024






 VTWM(1)                           X11R4-6                           VTWM(1)
                               Release 5.4.6b



      This search algorithm allows both twm(1) and vtwm to coexist
      peacefully at an installation.  Since vtwm is a superset of twm(1), it
      can even used to replace the latter, and users who have only a
      .twmrc-style file should not notice any difference.

      If no startup files are found, vtwm will use the built-in defaults
      described above.  The only X11 resource used by vtwm is bitmapFilePath
      for a colon-separated list of directories to search when looking for
      bitmap and pixmap files (for more information, see the Athena Widgets
      manual and xrdb(1)).

      vtwm startup files are logically broken up into three types of
      specifications:  Variables, Bindings, Menus.

      The Variables section must come first and is used to describe the
      fonts, colors, cursors, border widths, icon and window placement,
      highlighting, autoraising, layout of titles, warping, and use of the
      icon manager.

      The Bindings section usually comes second and is used to specify the
      functions that should be to be invoked when keyboard and pointer
      buttons are pressed in windows, icons, titles, and frames.

      The Menus section gives any user-defined menus (containing functions
      to be invoked or commands to be executed).

      Variable names and keywords are case-insensitive.  Strings must be
      surrounded by double quote characters (e.g., "blue") and are case-
      sensitive.  A sharp sign (#) outside of a string causes the remainder
      of the line in which the character appears to be treated as a comment.

 M4 PREPROCESSING
      A powerful feature of vtwm as of version 5.4.6 is that it can use
      m4(1) to pre-process it's startup files.  When vtwm is started with
      -m, it will open a file for input as described above, but will process
      that file through m4 before parsing it.  So, you can use m4 macros to
      perform operations at runtime.  This makes it very easy to work when
      you use many different displays, etc.  For example, if you want to set
      the lower right section of the screen to be your IconRegion, you can
      use m4 directives and pre-defined symbols to calculate the region you
      want:
           define(IRegion, translit(eval(WIDTH/3)*eval(HEIGHT/2)+eval(WIDTH-WIDTH/3)-0, *, x))
           IconRegion  "IRegion" SOUTH EAST 75 25
      will define the lower half, and right-hand third of the screen.  The
      symbols WIDTH and HEIGHT are calculated by vtwm for m4 to use.  The
      following symbols are pre-defined by vtwm:

      SERVERHOST     This variable is set to the name of the machine that is
                     running the X server.

      CLIENTHOST     The machine that is running the X clients (i.e.,

                     ProtocolRevision().

      VENDOR         The vendor of your X server (i.e., "MIT X Consortium").

      RELEASE        The release number of your X server.  For MIT X11R5,
                     this is "5".

      WIDTH          The width of your display in pixels.

      HEIGHT         The height of your display in pixels.

      X_RESOLUTION   The X resolution of your display in pixels per meter.

      Y_RESOLUTION   The Y resolution of your display in pixels per meter.

      PLANES         The number of bit planes your display supports in the
                     default root window.

      BITS_PER_RGB   The number of significant bits in an RGB color.  (log
                     base 2 of the number of distinct colors that can be
                     created.  This is often different from the number of
                     colors that can be displayed at once.)

      TWM_TYPE       Tells which twm derivative is running.  It will always
                     be set to "vtwm" in this program.  This is useful for
                     protecting parts of your startup file that twm proper
                     won't understand (like VirtualDesktop) so that it is
                     still usable with other twm-based programs.

      CLASS          Your visual class.  Will return one of "StaticGray",
                     "GrayScale", "StaticColor", "PseudoColor", "TrueColor",
                     "DirectColor", or, if it cannot determine what you
                     have, "NonStandard".

      COLOR          This will be either "Yes" or "No".  This is just a
                     wrapper around the above definition.  Returns "Yes" on
                     "*Color", and "No" on "StaticGray" and "GrayScale".

      XPM            This will be either "Yes" or "No" depending on whether
                     support for pixmap image files has been compiled in.

      SOUND          This will be either "Yes" or "No" depending on whether
                     support for sound has been compiled in.

      REGEX          This will be either "Yes" or "No" depending on whether
                     support for regular expressions ("RE"s) has been
                     compiled in.

      Note that any symbols passed to m4 on the command line that conflict
      with these will not be anticipated or dealt with by vtwm; you will be
      at the mercy of your particular m4.

      Note also that if vtwm's preparation for executing m4 fails, the
      startup file will be processed normally, and will choke on the first
      m4 macro encountered.

      Finally, be aware that m4 preprocessing can cause things often found
      in startup files to break.  For example, quotes and backquotes in
      shell commands will be badly messed up by m4's own internal quoting
      mechanism.  This particular problem can be worked around by placing
      changequote(,) at the top of your startup file.

 VARIABLES
      Many of the aspects of vtwm's user interface are controlled by
      variables that may be set in the user's startup file.  Some of the
      options are enabled or disabled simply by the presence of a particular
      keyword.  Other options require keywords, numbers, strings, or lists
      of all of these.

      Lists are surrounded by braces and are usually separated by whitespace
      or a newline.  For example:
           AutoRaise { "emacs" "VTWM*" "x*clock" "Xmh" "XTerm" }
      or
           AutoRaise
           {
                   "emacs"
                   "VTWM*"
                   "x*clock"
                   "Xmh"
                   "XTerm"
           }
      When a variable containing a list of strings representing windows is
      searched (e.g., to determine whether or not to enable autoraise as
      shown above), a string must be a case-sensitive match to the window's
      name (given by the WM_NAME window property), or the resource or class

      names (both given by the WM_CLASS window property).  The preceding
      example would enable autoraise on windows named "emacs", all vtwm-
      specific windows, any clocks installed whose name starts with an 'x'
      (asclock will not autoraise), and all xmh and xterm windows (which are
      of class "XTerm" and "Xmh", respectively).  See the WILDCARDS section
      for details on what the asterisks ('*') mean.

      String arguments that are interpreted as filenames (see the Pixmaps,
      Cursors, and IconDirectory variables below) will prepend the user's
      directory (specified by the HOME environment variable) if the first
      character is a tilde (~).  If, instead, the first character is a colon
      (:), the name is assumed to refer to one of the internal bitmaps that
      are used to create the default 2D titlebar buttons:  :xlogo and
      :delete, :iconify and :dot, :resize, :menu, :darrow, :rarrow, and
      :question (used for non-existent bitmap files).  Finally, if the first
      five characters are ":xpm:", the name is assumed to refer to one of
      the internal pixmaps that are used to create the default 3D titlebar
      buttons: :xpm:dot, :xpm:resize, :xpm:menu, :xpm:zoom, :xpm:bar,
      :xpm:darrow, and :xpm:rarrow.

      The following variables may be specified at the top of a vtwm startup
      file.  Lists of Window name prefix strings are indicated by win-list.
      Optional arguments are shown in square brackets:

      AppletRegion geomstr vgrav hgrav hgrid vgrid { win-list }
           This variable specifies an area on the root window in which the
           windows listed in win-list are placed.  The geomstr is a quoted
           string containing a standard geometry specification for the
           region size and location.  If more than one AppletRegion is
           specified, windows will be put into succeeding regions that have
           the window listed when the first is full.  The vgrav argument
           should be either North or South and is used to control whether
           windows are first filled in from the top or bottom of the region.
           Similarly, the hgrav argument should be either East or West and
           is used to control whether windows should be filled in from the
           left or right.  Windows are laid out in a grid with cells hgrid
           pixels wide and vgrid pixels high.  Note that the smallest
           dimension of the region must be at least the size of the largest
           window in it, including frame and titlebar, in the same
           direction.  This variable is intended to simplify management of
           all those little tool applications like xcb(1), xbiff(1),
           xload(1), etc. that are used regularly.

      AutoPan N
              This variable allows the screen to automatically pan by N% of
              a real screen when the mouse approaches the edge of the
              screen.   The pan will be in the direction of the edge
              approached.  On reasonably fast machines a value of 5 is nice.

              screen is panned.  The default value is 5.

      AutoPanExtraWarp pixels
              If AutoPan is turned on and NaturalAutopanBehavior turned off,
              this variable specifies how far, in pixels, you want the mouse
              to move away from the inner edge of the autopan border when
              autopanning.  The default value is 2 pixels.

      AutoPanWarpWithRespectToRealScreen N
              With this option turned on, the pointer is warped by N% as
              many pixels on the real screen as the screen is scrolled, or
              by
              (AutoPanBorderWidth + AutoPanExtraWarp)

              a more thorough discussion of this and some recommended
              settings.

      AutoRaise [{ win-list }]
              This variable specifies a list of windows (all windows if the
              list is defaulted) to be automatically raised whenever the
              pointer has come to rest in a window for the amount of time
              specified by the RaiseDelay variable.  This action can be
              interactively enabled or disabled on individual windows using
              the function f.autoraise.

      AutoRaiseDelay milliseconds
              For windows that are to be automatically raised when the
              pointer enters (see the AutoRaise variable and the f.autoraise
              function) this variable specifies the length of time the
              pointer should rest in the window before it is raised.  The
              default is 0 milliseconds. but 400 milliseconds works well
              too.

      AutoRelativeResize
              This variable indicates that dragging out a window size
              (either when initially sizing the window with pointer Button2
              or when resizing it) should not wait until the pointer has
              crossed the window edges.  Instead, moving the pointer
              automatically causes the nearest edge or edges to move by the
              same amount.  This allows the resizing windows that extend off
              the edge of the screen.  If the pointer is in the center of
              the window, or if the resize is begun by pressing a
              titlebutton, vtwm will still wait for the pointer to cross a
              window edge (to prevent accidents).  This option is
              particularly useful for people who like the press-drag-release
              method of sweeping out window sizes.

              on colormap allocations.

      BorderBevelWidth pixels
              Tells vtwm to use 3D-looking window borders.  It specifies the
              width in pixels of the bevel.  The color of the 3D border is
              BorderTileBackground, and if NoHighlight is not selected, the
              border of the Focus window is BorderColor.  The default is 0.

      BorderColor string [{ wincolorlist }]
              This variable specifies the default color of the border to be
              placed around all non-iconified windows, and may only be given
              within a Color or Monochrome list.  The optional wincolorlist
              specifies a list of window and color name pairs for specifying
              particular border colors for different types of windows.  For
              example:
              BorderColor "gray50"

              The default is "black".

      BorderTileBackground string [{ wincolorlist }]
              This variable specifies the default background color in the
              gray pattern used in unhighlighted borders (only if
              NoHighlight hasn't been set), and may only be given within a
              Color or Monochrome list.  The optional wincolorlist allows
              per-window colors to be specified.  The default is "white".

      BorderTileForeground string [{ wincolorlist }]
              This variable specifies the default foreground color in the
              gray pattern used in unhighlighted borders (only if
              NoHighlight hasn't been set), and may only be given within a
              Color or Monochrome list.  The optional wincolorlist allows
              per-window colors to be specified.  The default is "black".

      BorderWidth pixels
              This variable specifies the width in pixels of the border
              surrounding all client window frames if ClientBorderWidth has
              not been specified.  This value is also used to set the border
              size of windows created by vtwm (such as the icon manager).
              The default is 2.

      ButtonBevelWidth pixels
              Tells vtwm to use 3D-looking window buttons. It specifies the

              should be indented on all sides.  Positive values cause the
              buttons to be smaller than the window text and highlight area
              so that they stand out.  Setting this and the
              TitleButtonBorderWidth variables to 0 makes titlebuttons be as
              tall and wide as possible.  The default is 1.

      ButtonColorIsFrame
              This variable specifies that the titlebar buttons will be the
              same color as the window frame.

      ClearBevelContrast contrast
              Indicates to vtwm how to calculate the clear bevel color for
              3D items.  The value is a compressed to the range 0 and 100.
              The formula used is:
              clear.{RGB} = (65535 - color.{RGB}) * (contrast / 100).

      ClientBorderWidth
              This variable indicates that border width of a window's frame
              should be set to the initial border width of the window,
              rather than to the value of BorderWidth.

      Color { colors-list }
              This variable specifies a list of color assignments to be made
              if the default display is capable of displaying more than
              simple black and white.  The colors-list is made up of the

              All of these color variables may also be specified for the
              Monochrome variable, allowing the same initialization file to
              be used on both color and monochrome displays.

      ConstrainedMoveTime milliseconds
              This variable specifies the length of time between button
              clicks needed to begin a constrained move operation.  Double
              clicking within this amount of time when invoking f.move will
              cause the window only to be moved in a horizontal or vertical
              direction.  Setting this value to 0 will disable constrained
              moves.  The default is 400 milliseconds.

      Cursors { cursor-list }
              This variable specifies the glyphs that vtwm should use for
              various pointer cursors.  Each cursor may be defined either
              from the cursor font or from two bitmap files.  Shapes from
              the cursor font may be specified directly as:
              cursorname        "string"

              where cursorname is one of the cursor names listed below, and
              string is the name of a glyph as found in the file
              /usr/include/X11/cursorfont.h (without the "XC_" prefix).  If
              the cursor is to be defined from bitmap files, the following
              syntax is used instead:
              cursorname        "image"   "mask"

              The image and mask strings specify the names of files
              containing the glyph image and mask in bitmap(1) form.  The
              bitmap files are located in the same manner as icon bitmap
              files.  The following example shows the default cursor
              definitions:

              This variable indicates that transient windows (those
              containing a WM_TRANSIENT_FOR property) should have titlebars.
              By default, transients are not reparented.

      DefaultBackground string

              This variable specifies the foreground color to be used for
              sizing and information windows.  The default is "black".

      DeiconifyToScreen
              When deiconifying a window, by default, the window will be
              placed at its previous geometry in the virtual desktop. With
              this variable set, vtwm ensures that the window will be placed
              somewhere on the real screen.

      DesktopDisplayBackground color [{ win-list }]
              This variable sets the backgrounds of the little windows
              inside the Virtual Desktop window, AND it sets the backgrounds
              of menu entries in the VTWM Windows menu -- unless you specify
              OldFashionedVtwmWindowsMenu.  The default color is used for
              the default background of windows not named in the list.  The
              optional win-list is a list of window names and colors, for
              example:
              DesktopDisplayBackground "purple"
              {
                  "zwgc"    "green"
              }

      DesktopDisplayBorder color [{ win-list }]
              This variable sets the border color in the virtual desktop
              representation window to color.  The win-list is in the same
              format as TitleForeground and other similar variables.

              This variable sees that iconified transient windows of an
              iconified parent window aren't deiconified when that parent
              is, thus preserving their state.  Default behavior is to
              deiconify all transient subwindows of the ancestor window when
              it is deiconified.

      DontIconifyByUnmapping { win-list }
              This variable specifies a list of windows that should not be
              iconified by simply unmapping the window (as would be the case
              if IconifyByUnmapping had been set).  This is frequently used
              to force some windows to be treated as icons while other
              windows are handled by the icon manager.

      DontInterpolateTitles
              This variable specifies a modification to the
              InterpolateMenuColors behavior.  It will cause vtwm to not
              apply color interpolation to any titles in the middle of the
              menu.  So, f.title strings that appear in the middle of the
              menu (ie, without a specific color defined for them) will
              inherit the default MenuTitle foreground and background

              Windows with the name winname appear with geometry and
              position as defined in location, and warp the user to jumpTo

              vtwm.  You would have to append " &" to all of your variables
              in order to execute them without blocking the window manager.
              With this option turned on, you don't have to; vtwm will
              automatically append " &" to the f.exec variable unless the
              last non-space character is either '&' or (in case you still
              want a command to block the window manager) ';'.

              For example, in a variable such as:
              f.exec "foo; bar; baz"

              the window manager will be blocked so that "foo" and "bar" can
              be executed; "baz" is the only command which will NOT block
              the window manager.  If you want all these commands to be
              backgrounded, try the following:
              f.exec "{ foo; bar; baz }" # note that "{" and "}"
                                         # are shell keywords; they
                                         # MUST be separated by
                                         # spaces.

              If you still want a command to block the window manager, you
              would use:
              f.exec "xset fp rehash;" # vtwm will not append " &"
                                       # because ';' is the last
                                       # non-space character.

      FixTransientVirtualGeometries
              These are bug workarounds that *should* fix the way most
              windows' virtual geometries are handled, i.e., they should be
              on the real screen if the parent windows are on the real
              screen, no matter where the virtual desktop is (xv(1) is one
              example of how these don't work).

      ForceIcons
              This variable indicates that icon image files specified in the

              optional win-list is a list of window names and colors so that
              per-window colors may be specified.  See the BorderColor
              variable for a complete description of the win-list.  The
              default is "white".

      IconBevelWidth pixels
              Tells vtwm to use 3D-looking icons, in which case the default
              value of IconBorderWidth is set to 0. It specifies the width
              in pixels of the bevel.  The default is 0.

              optional win-list is provided, only those windows will be
              iconified by simply unmapping.  Windows that have both this
              and the IconManagerDontShow options set may not be accessible
              unless the user has provided bindings to the warp functions
              (f.warp and the like) while WarpUnmapped is set, or by the

              0.

      IconManagerDontShow [{ win-list }]
              This variable indicates that the icon manager should not
              display any windows.  If the optional win-list is given, only
              those windows will not be displayed.  This variable is used to
              prevent windows that are rarely iconified (such as xclock or
              xload) from taking up space in the icon manager.

              description of the win-list.  The default is "black".

      IconManagerGeometry string [ columns ]
              This variable specifies the geometry of the icon manager
              window.  The string argument is standard geometry
              specification that indicates the initial full size of the icon
              manager.  The icon manager window is then broken into columns
              pieces and scaled according to the number of entries in the
              icon manager.  Extra entries are wrapped to form additional
              rows.  The default number of columns is 1.

      IconManagerHighlight string [{ win-list }]
              This variable specifies the border color to be used when
              highlighting the icon manager entry that currently has the
              focus, and can only be specified inside of a Color or

      IconManagers { iconmgr-list }
              This variable specifies a list of icon managers to create.
              Each item in the iconmgr-list has the following format:
              "winname" ["iconname"]      "geometry" columns

              where winname is the name of the windows that should be put
              into this icon manager, iconname is the name of that icon
              manager window's icon, geometry is a standard geometry
              specification, and columns is the number of columns in this
              icon manager as described in IconManagerGeometry.  For
              example:
              IconManagers
              {
                      "XTerm"      "300x5+800+5"  5
                      "myhost"     "400x5+100+5"  2
              }

              Clients whose name or class is "XTerm" will have an entry
              created in the "XTerm" icon manager.  Clients whose name was
              "myhost" would be put into the "myhost" icon manager.

      IconManagerShow { win-list }
              This variable specifies a list of windows that should appear
              in the icon manager.  When used in conjunction with the
              IconManagerDontShow variable, only the windows in this list
              will be shown in the icon manager.

      IconRegion geomstr vgrav hgrav hgrid vgrid

              the client.  The geomstr is a quoted string containing a
              standard geometry specification for the region size and
              location.  If more than one IconRegion line is given, icons
              will be put into the succeeding regions when the first is
              full.  The vgrav argument should be either North or South and
              is used to control whether icons are first filled in from the
              top or bottom of the region.  Similarly, the hgrav argument
              should be either East or West and is used to control whether
              icons should be filled in from the left or right.  Icons are
              laid out in a grid with cells hgrid pixels wide and vgrid
              pixels high.  Note that the smallest dimension of the region
              must be at least the size of the largest icon in it in the
              same direction.  Note also that many applications change their
              icon name as they run, and no provision is made to reformat
              the icon regions if any icon changes size accordingly.

      Icons { win-list }
              This variable specifies a list of window names and the image
              filenames that should be used as their icons.  For example:
              Icons
              {
                      "XTerm"         "xterm.icon"
                      "xfd"           "xfd_icon"
              }

              Windows that match "XTerm" and would not be iconified by
              unmapping, and would try to use the icon image in the file
              "xterm.icon".  If ForceIcons is specified, this image will be
              used even if the client has requested its own icon image.

      InfoBevelWidth pixels
              Tells vtwm to use 3D-looking identify, move and resize
              windows.  It specifies the width in pixels of the bevel.  The
              default is 0.

      InfoFont string
              This variable specifies the font to be used for in the
              identify window.  The default is "fixed".

      InterpolateMenuColors
              This variable indicates that menu entry colors should be
              interpolated between entry specified colors.  In the example
              below:
              Menu "mymenu"
              {
                      "Title"         ("black":"red")         f.title

              the foreground colors for "entry1" and "entry2" will be
              interpolated between black and white, and the background
              colors between red and green.  Similarly, the foreground for
              "entry4" will be half-way between white and red, and the
              background will be half-way between green and white.

      LessRandomZoomZoom
              With this option turned on, this makes random zooms a bit less

              windows when NoTitle has been set.

      MaxWindowSize string
              This variable specifies a geometry in which the width and
              height give the maximum size for a given window.  This is
              typically used to restrict windows to the size of the screen.
              The default is "30000x30000".

      MenuFont string
              This variable specifies the font to use when displaying menus.
              The default is "variable".

      MenuForeground string
              This variable specifies the foreground color used for menus,
              and can only be specified inside of a Color or Monochrome
              list.  The default is "black".

      MenuScrollBorderWidth pixels

              pixels on the real screen.  With this option turned on, the
              pointer is warped on the real screen by as many pixels as the
              screen is scrolled, or the above value, whichever is greater.
              Thus, the pointer does not normally move very much (only by
              AutoPanExtraWarp) in relation to the virtual desktop.

              This works really well on faster X terminals and workstations,
              although for slower ones, you may want to use the following:
              AutoPanWarpWithRespectToRealScreen 50

              to achieve a similar effect.  Setting NaturalAutopanBehavior
              has the exact same effect as using the variable
              AutoPanWarpWithRespectToRealScreen 100

      NoBackingStore
              This variable indicates that vtwm's windows should not request
              backing store to minimize repainting.  This is typically used
              with servers that can repaint faster than they can handle
              backing store.

      NoBorder [{ win-list }]
              This variable indicates that windows should not have borders.
              If the optional win-list is given, only those windows will not
              have borders.

      NoCaseSensitive
              This variable indicates that case should be ignored when
              sorting icon names in an icon manager.  This option is
              typically used with applications that capitalize the first
              letter of their icon name.

      NoDefaultMouseOrKeyboardBindings
              This variable indicates that vtwm should not supply the
              default mouse and keyboard bindings.  This option should only
              be used if the startup file contains a completely new set of
              mouse and keyboard bindings and definitions.  See also
              NoDefaults.

      NoDefaults
              This variable indicates that vtwm should not supply the
              default titlebuttons and bindings.  This option should only be
              used if the startup file contains a completely new set of
              bindings and definitions.  This function has the effect of
              setting both NoDefaultMouseOrKeyboardBindings and
              NoDefaultTitleButtons.

      NoDefaultTitleButtons
              This variable indicates that vtwm should not supply the
              default titlebuttons.  This option should only be used if the
              startup file contains a completely new set of titlebutton
              definitions.  See also NoDefaults.

      NoGrabServer
              This variable indicates that vtwm should not grab the server
              when popping up menus and moving or resizing windows.

      NoHighlight [{ win-list }]
              This variable indicates that borders should not be highlighted
              to track the location of the pointer.  If the optional win-
              list is given, highlighting will only be disabled for those
              windows.  When the border is highlighted, it will be drawn in
              the current BorderColor.  When the border is not highlighted,
              it will be stippled with an gray pattern using the current
              BorderTileForeground and BorderTileBackground colors.

      NoIconManagerFocus
              This variable indicates that vtwm should not set focus to
              windows corresponding to their entries in an icon manager.
              Normally, vtwm sets the focus so that events from an icon
              manager are delivered to the application.  Typically, this is
              set to facilitate icon manager bindings that would otherwise
              be delivered to the application.

      NoIconManagerHighlight
              This variable indicates that icon manager entries will not be
              highlighted to track the location of the pointer. This is
              independant of the NoHighlight variable.

      NoIconManagers
              This variable indicates that no icon manager should be
              created.

      NoIconifyIconManagers
              This variable indicates that no icon manager should be
              iconified.

      NoMenuShadows
              This variable indicates that menus should not have drop
              shadows drawn behind them.  This is typically used with slower
              servers since it speeds up menu drawing at the expense of
              making the menu slightly harder to read.

      NoOpaqueMove [{ win-list }]

      NoOpaqueResize [{ win-list }]
              These variables indicate that the f.move and f.resize
              functions should change just a window's outline.  If the
              optional win-list is given, only those windows will be
              affected. These are usually used to narrow the scope of
              "global" OpaqueMove and OpaqueResize variables.

              edge of short titlebars and icon managers. Disables the
              default behavior of using ellipses to indicate a truncated
              title.

      NoRaiseOnDeiconify
              This variable indicates that windows that are deiconified
              should not be raised.

      NoRaiseOnMove
              This variable indicates that windows should not be raised when
              moved.  This is typically used to allow windows to slide
              underneath each other.

      NoRaiseOnResize
              This variable indicates that windows should not be raised when
              resized.  This is typically used to allow windows to be
              resized underneath each other.

      NoRaiseOnWarp
              This variable indicates that windows should not be raised when
              the pointer is warped to them with the warp functions (f.warp
              and the like) is set.  If this option is set, warping to an
              occluded window may result in the pointer ending up in the
              occluding window instead the desired window when WarpUnmapped
              is not set.

      NoSaveUnders
              This variable indicates that menus should not request save-
              unders to minimize window repainting following menu selection.
              It is typically used with displays that can repaint faster
              than they can handle save-unders.

      NoStackMode [{ win-list }]
              This variable indicates that client window requests to change
              stacking order should be ignored.  If the optional win-list is
              given, only requests on those windows will be ignored.  This
              is typically used to prevent applications from relentlessly
              popping themselves to the front of the window stack.

      NoTitle [{ win-list }]
              This variable indicates that windows should not have
              titlebars.  If the optional win-list is given, only those
              windows will not have titlebars.  MakeTitle may be used with
              this option to force titlebars to be put on specific windows.

      NoTitleFocus
              This variable indicates that vtwm should not set keyboard
              input focus to each window as it is entered.  Normally, vtwm
              sets the focus so that focus and key events from the titlebar
              and icon managers are delivered to the application.  If the
              pointer is moved quickly and vtwm is slow to respond, input

              can be directed to the old window instead of the new.  This
              option is typically used to prevent this "input lag" and to
              work around bugs in older applications that have problems with
              focus events.

      NoTitleHighlight [{ win-list }]
              This variable indicates that the highlight area of the
              titlebar, which is used to indicate the window that currently
              has the input focus, should not be displayed.  If the optional
              win-list is given, only those windows will not have highlight
              areas.  This and the SqueezeTitle options can be set to
              substantially reduce the amount of screen space required by
              titlebars.

      NotVirtualGeometries
              This variable indicates that vtwm should assume that user
              geometries should be relative to the current virtual window,
              as opposed to absolute.  If you set this, then "xterm
              -geometry +20+20" specifies a position in the current view;
              otherwise, and by default, it would specify a position in the
              top-left view.

      OldFashionedTwmWindowsMenu

      OldFashionedVtwmWindowsMenu
              By default, the VTWM Windows menu will use the same colors
              that you see in the panner. This variable disables that
              behavior.

      OpaqueMove [{ win-list }]

      OpaqueResize [{ win-list }]
              These variables indicate that the f.move and f.resize
              functions should actually change the window instead of just an
              outline so that the user can immediately see what the window
              will look like.  If the optional win-list is given, only those
              windows will be affected "opaquely".  These options are
              typically used on fast systems (particularly when NoGrabServer
              is set).

      PanDistanceX N

      PanDistanceY N
              These variables define a grid of screens for the virtual
              desktop, expressed as N% of a real screen.  When the f.snap
              function is called, the real screen will be moved to the
              closest grid location.  The (mis)naming of these variables is
              for historical reasons.

      PanResistance milliseconds

              adjacent virtual screen.  It specifies how long the pointer
              must be within AutoPanBorderWidth pixels of the real screen's
              edge.  Values equal to 0 or greater than 10000 disables this
              feature.  The default is 0 milliseconds.

      PauseOnExit N

      PauseOnQuit N
              These variables define a delay on exit, expressed in seconds.
              They allow the (vtwm stop) and f.quit sounds time to play
              before the connection to rplayd(8) is closed.

      Pixmaps { pixmaps }
              This variable specifies a list of image filenames that define
              the appearance of various windows.  Each entry is a keyword
              indicating the window to set, followed by a string giving the
              name of the image file.  The following windows may be
              specified thus:
              Pixmaps
              {
                      TitleHighlight  "gray1"
                      RealScreenPixmap "something"
                      VirtualBackgroundPixmap "something else"
              }

              The default for TitleHighlight is to use an even stipple
              pattern.

      PrettyZoom
              If Zoom is turned on, this makes the associated animation look
              just a little nicer, depending on your personal taste.  This
              makes the zoom slower, however, so you may have to decrease
              the value of the Zoom variable.

      RaiseDelay milliseconds
              For windows that are to be automatically raised when the
              pointer enters (see the AutoRaise variable and the f.autoraise
              function) this variable specifies the length of time the
              pointer should rest in the window before it is raised.  The
              default is 0 milliseconds.  400 milliseconds works well.

      RandomPlacement
              This variable indicates that windows with no specified
              geometry should be placed in a pseudo-random location instead
              of having the user drag an outline (or the window itself if
              the OpaqueMove variable is set) to the preferred location.

      RealScreenBackground string
              See RealScreenForeground.

      RealScreenBorderWidth pixels
              This value specifies the border width of the RealScreen window
              (see RealScreenForeground). The default value is 0 pixels.

      RealScreenForeground string
              Inside what vtwm calls the virtual desktop window, but which
              we might call the "panner", is a little window that shows
              where the physical screen is located in virtual space.  The
              vtwm source code calls this little window the RealScreen.  By
              default, it has no border, and can be distinguished from the
              normal backdrop of the panner only by its color or image.  Its
              foreground color has no meaning unless you give it an image.
              (It can be given a border with RealScreenBorderWidth.)

      RealScreenPixmap string
              Names an image file used to decorate the RealScreen window.  A
              sample is provided, nestedsqu.xbm, but your mileage may vary
              as the size of your screen varies!  It is easy to find out the
              size of this window and to create any image file of type
              bitmap(1) or pixmap(1) for it; that is the recommended
              procedure.

      ResizeFont string
              This variable specifies the font to be used for in the
              dimensions window when resizing windows.  The default is
              "fixed".

      ResizeRegion location
              This variable specifies the area on the screen to display the
              resize window.  The location should be one of NorthWest,
              NorthEast, SouthWest, SouthEast, or Centered.

      RestartPreviousState
              This variable indicates that vtwm should attempt to use the
              WM_STATE property on client windows to tell which windows
              should be iconified and which should be left visible.  This is
              typically used to try to regenerate the state that the screen
              was in before the previous window manager was shutdown.

      RightHandSidePulldownMenus
              By default, pull-down menus start from the left-to-right
              center of their parent pull-down menus (if they have them).
              With this option turned on, they will start closer to the
              right-hand side of the parent menu.  This behavior was
              inspired by that exhibited by pull-down menus in other GUIs.

      SaveColor { colors-list }
              This variable indicates a list of color assignments to be
              stored as pixel values in the root window property
              _MIT_PRIORITY_COLORS.  Clients may elect to preserve these
              values when installing their own colormap.  Note that use of

              this mechanism is a way an for application to avoid the
              "technicolor" problem, whereby useful screen objects such as
              window borders and titlebars disappear when a programs custom
              colors are installed by the window manager.  For example:
              SaveColor
              {
                      BorderColor
                      TitleBackground
                      TitleForeground
                      "red"
                      "green"
                      "blue"
              }

              This would place on the root window 3 pixel values for borders
              and titlebars, as well as the three color strings, all taken
              from the default colormap.

      ShallowReliefWindowButton
              This indicates to vtwm that 3D window titlebar buttons (and
              the title highlight bar if SunkFocusWindowTitle is used)
              should be rendered with a "flatter" appearance.

      ShowIconManager
              This variable indicates that the icon manager window should be
              displayed when vtwm is started.  It can always be brought up
              using the f.showiconmgr function.

      SnapRealScreen
              This variable causes the real screen to snap to a grid defined
              in PanDistanceX and PanDistanceY increments whenever the
              representation moves. The f.snaprealscreen function can be
              used to toggle this setting.

      SortIconManager
              This variable indicates that entries in the icon manager
              should be sorted alphabetically rather than by simply
              appending new windows to the end.

      SoundHost string
              This variable specifies what machine (by its TCP/IP hostname)
              is running the rplayd(8) daemon. If not specified, the local
              machine is tried. If rplayd(8) cannot be accessed, sound will
              be toggled off.

      Sounds { sound-list }
              This variable is a list of identifiers and associated sound
              files. It contains entries of the form:

                               Release 5.4.6b



              where identifier is any function described in the BINDINGS
              section except f.sounds and f.separator, as well as the
              following event identifiers: (vtwm start), (vtwm stop),
              (client map), (client unmap), (menu map), (menu unmap), (info
              unmap), (autopan event), and (bell event). The soundfile is
              the full pathname of the sound file to play for the associated
              identifier, and volume sets the volume for which to play that
              sound (see also SoundVolume). Note that the list entries must
              be quoted:
              Sounds
              {
                      "(vtwm start)"    "/usr/local/share/sound/wowee.wav"
                      "(vtwm stop)"     "/usr/local/share/sound/seeya.wav"
                      "f.exec"          "/usr/local/share/sound/click.au"   50
                      "(client map)"    "/usr/local/share/sound/ping.au"    50
                      "f.delete"        "/usr/local/share/sound/doh1.wav"
                      "f.deletedoor"    "/usr/local/share/sound/doh2.wav"
                      "f.destroy"       "/usr/local/share/sound/doh3.wav"
                      "(client unmap)"  "/usr/local/share/sound/ping.au"
              }

              This example points out that some identifiers "overlap":
                f.beep > (bell event)            f.exec > (client map)
                f.delete > (client unmap)        f.menu > (menu map)
                f.deletedoor > (client unmap)    f.quit > (vtwm stop)
                f.destroy > (client unmap)       f.version = f.identify

              In these cases, the function takes precedence over the event
              when both would otherwise play.

      SoundVolume N
              This variable sets the overall volume for which to play
              sounds, expressed as N% of maximum. Default is 25 (1/4
              attenuation).

      SqueezeTitle [{ squeeze-list }]
              This variable indicates that vtwm should attempt to use the
              SHAPE extension to make titlebars occupy only as much screen
              space as they need, rather than extending all the way across
              the top of the window.  The optional squeeze-list may be used
              to control the location of the squeezed titlebar along the top
              of the window.  It contains entries of the form:
              "name"            justification     num       denom

              where name is a window name, justification is either left,
              center, or right, and num and denom are numbers specifying a
              ratio for the relative position about which the titlebar is
              located, measured from left to right.  A ratio of 0/0
              indicates that the justification is absolute, A non-zero
              numerator with a zero denominator indicates a pixel count, and
              the justification is ignored entirely for any other ratio.

                               Release 5.4.6b



              For example:
              SqueezeTitle
              {
                      "XTerm"         left            0       0
                      "xterm1"        left            1       3

              }

              The DontSqueezeTitle list can be used to turn off squeezing on
              certain titles.

      StartIconified [{ win-list }]
              This variable indicates that client windows should initially
              be left as icons until explicitly deiconified by the user.  If
              the optional win-list is given, only those windows will be
              started iconic.  This is useful for programs that do not
              support an -iconic command line option or resource.

      StaticIconPositions
              This variable alters icon placement such that they will
              maintain their positions on the virtual desktop when not
              nailed and DeiconifyToScreen is not used.  This is most
              applicable when SnapRealScreen and AutoPan is used with
              PanDistanceX and PanDistanceY values to simulate ctwm(1)
              workspaces.

      StayUpMenus
              This variable alters menu interaction.  By default, a menu
              item is selected when a mouse button is released over it.
              This variable causes menu items to be selected on the next
              button press event.

      StayUpOptionalMenus
              This variable is similar to StayUpMenus, except that if any
              menu items are selected, the menu interaction reverts to the
              old behavior.  For example, suppose you have the right mouse
              button bound to bring up a menu with a title bar.  Clicking
              the right button and releasing it (over the title bar) will
              bring up the menu and have it stay up until you click on a
              menu item.  Clicking the right button, moving the pointer to a
              menu item, and releasing the right button will activate that
              menu item and dismiss the menu.

      StrictIconManager
              This variable causes icon managers to list only those windows
              that are in an iconified state.

      SunkFocusWindowTitle
              This variable specifies that the title highlight bar of the
              focus window (if exists) should be of a sunken appearance
              instead of a bitmap or image.  Only valid if TitleBevelWidth
              is non-zero.

      TitleBackground string [{ win-list }]
              This variable specifies the background color used in
              titlebars, and may only be specified inside of a Color or
              Monochrome list.  The optional win-list is a list of window
              names and colors so that per-window colors may be specified.
              The default is "white".

      TitleBevelWidth pixels
              Tells vtwm to use 3D-looking titlebars, in which case the
              default values of TitleButtonBorderWidth, FramePadding,
              TitlePadding and ButtonIndent are set to 0.  It specifies the
              width in pixels of the bevel.  The default is 0.

      TitleButtonBorderWidth pixels
              This variable specifies the width in pixels of the border
              surrounding titlebuttons.  This is typically set to 0 to allow
              titlebuttons to take up as much space as possible and to not
              have a border.  The default is 1.

      TitleFont string
              This variable specifies the font to used for displaying window
              names in titlebars.  The default is "variable".

      TitleForeground string [{ win-list }]
              This variable specifies the foreground color used in
              titlebars, and may only be specified inside of a Color or
              Monochrome list.  The optional win-list is a list of window
              names and colors so that per-window colors may be specified.
              The default is "black".

      TitlePadding pixels
              This variable specifies the distance between the various
              buttons, text, and highlight areas in the titlebar.  The
              default is 8 pixels.

      UnknownIcon string
              This variable specifies the filename of an image  file to be
              used as the default icon.  This image will be used as the icon
              of all clients which do not provide an icon image and are not
              listed in the Icons list.

      UsePPosition string
              This variable specifies whether or not vtwm should honor
              program-requested locations (given by the PPosition flag in
              the WM_NORMAL_HINTS property) in the absence of a user-
              specified position.  The argument string may have one of three
              values:  "off" (the default) indicating that vtwm should
              ignore the program-supplied position, "on" indicating that the
              position should be used, and "non-zero" indicating that the
              position should used if it is other than (0,0).  The latter
              option is for working around a bug in older toolkits.

      VirtualBackground string
              This is the background color for the panner, a.k.a. the
              Virtual Desktop window.

      VirtualBackgroundPixmap string
              Names an image file to decorate the panner.  See also the
              nexpm program.

      VirtualForeground string
              Foreground for the panner; has no use unless you specify a
              panner image of type bitmap(1).

      VirtualDesktop geometry scale
              This variable must be set to enable the virtual desktop
              features of vtwm. If this variable is not set, vtwm will
              behave in the same manner as twm. This variable specifies
              where to place the virtual desktop window and its size. The
              geometry is a standard X geometry specification and defines
              the size and location of the window containing the desktop
              representation.

              The scale parameter specifies the scaling of the virtual
              desktop window compared to the desktop. The size specification
              can be given in three ways. If size is larger than the screen
              size, it represents the size of the whole desktop. The virtual
              window desktop size will then be size divided by scale. When
              size times scale is smaller than the screen size, size
              represents the number of screens that should fit in the
              desktop. Otherwise size represents the size of the virtual
              desktop window. The currently accessible virtual desktop is
              then scale times the size of the desktop window. In the
              following example, a scale of 20 (with a screen size of say
              1152x900) means that the desktop area is 20 times the size of
              the desktop window: the desktop area will be 4000x4000.
              VirtualDesktop "200x200+10+10" 20

              The size of the desktop can be changed dynamically, by simply
              resizing the virtual desktop window.

      VirtualDesktopBevelWidth pixels
              Tells vtwm to use a 3D-looking virtual desktop. It specifies
              the width in pixels of the bevel.  The default is 0.

      VirtualDesktopFont font
              This variable causes font to be used when displaying the names
              of windows in the virtual desktop display.  If this variable
              is not set, then names will not be displayed.  The
              DesktopDisplayForeground should also be set for this feature
              to be useful.

      VirtualReceivesMotionEvents

      VirtualSendsMotionEvents
              These variables indicate that changes to the position and
              dimension of windows on the real screen will be reflected in
              the virtual desktop as they occur, and visa-versa.

      WarpCursor [{ win-list }]
              This variable indicates that the pointer should be warped into
              windows when they are deiconified.  If the optional win-list
              is given, the pointer will only be warped when those windows
              are deiconified.

      WarpSnug
              With this variable set, the warp functions (f.warp and the
              like) will fit the entire window on the screen, i.e., they'll
              be snugged on the real screen.

      WarpToTransients
              This variable indicates that the pointer should be warped into
              transient windows when they are created.

      WarpUnmapped
              This variable indicates that the warp functions (f.warp and
              the like) should deiconify any iconified windows they
              encounter.  This is typically used to make a key binding that
              will pop a particular window (such as xmh), no matter where it
              is.  The default is for the functions to ignore iconified
              windows.

      WarpVisible
              This variable indicates that the warp functions
              f.warpclassnext, f.warpclassprev, f.warpring, and f.warpto
              should restrict themselves to windows that are on the screen.
              The default is for the functions to traverse the entire
              virtual desktop.

      WarpWindows
              When warping to a window, by default the real screen will be
              moved to find the window on the virtual desktop. With this

              set, the window itself will be warped to the real screen,
              moving the window in the virtual desktop.

      WindowRing { win-list }
              This variable specifies a list of windows along which the
              f.warpring function cycles. If no list is specified, then all
              windows are included in the window ring.

      XorValue number
              This variable specifies the value to use when drawing window
              outlines for moving and resizing.  This should be set to a
              value that will result in a variety of distinguishable colors
              when exclusive-or'ed with the contents of the user's typical
              screen.  Setting this variable to 1 often gives nice results
              if adjacent colors in the default colormap are distinct.  By
              default, vtwm will attempt to cause temporary lines to appear
              at the opposite end of the colormap from the graphics.

      Zoom [ count ]
              This variable indicates that outlines suggesting movement of a
              window to and from its iconified state should be displayed
              whenever a window is iconified or deiconified.  The optional
              count argument specifies the number of outlines to be drawn.
              The default count is 8.

      ZoomZoom
              This variable modifies zooms such that a random place will be
              used for the source or destination when there isn't an
              appropriate window (e.g., an icon, icon manager entry, or
              client window).  Default behavior inhibits zooms when there
              aren't appropriate windows, except for the f.zoomzoom
              function.

 SPECIAL VARIABLES
      The following variables must be set after the fonts have been
      assigned, so it is usually best to put them at the end of the
      variables or beginning of the bindings sections:

      DefaultFunction function
              This variable specifies the function to be executed when a key
              or button event is received for which no binding is provided.
              This is typically bound to f.nop, f.beep, or a menu containing
              window operations.

      WindowFunction function
              This variable specifies the function to execute when a window
              is selected from the VTWM Windows menu.  If this variable is
              not set (default), the window will be deiconified and raised.
              It is strongly recommended that if this is set, the function
              includes provision for deiconifying windows.

 BINDINGS
      After the desired variables have been set, functions may be attached
      titlebuttons and key and pointer buttons.  Titlebuttons may be added
      from the left or right side and appear in the titlebar from left-to-
      right according to the order in which they are specified.  Key and
      pointer button bindings may be given in any order.

      Titlebuttons specifications must include the name of the image to use
      in the button box and the function to be invoked when a pointer button
      is pressed within them:
           LeftTitleButton "bitmapname"      = function
      or
           RightTitleButton "bitmapname"     = function

      The bitmapname may refer to one of the built-in bitmaps (which are
      scaled to match TitleFont) by using the appropriate colon-prefixed
      name described above, otherwise an external file is expected.

      Key and pointer button specifications must give the modifiers that
      must be pressed, over which parts of the screen the pointer must be,
      and what function is to be invoked.  Keys are given as strings
      containing the appropriate keysym name; buttons are given as the
      keywords Button1-Button5:
           "FP1"           = modlist : context : function
           Button1 = modlist : context : function

      The modlist is any combination of the modifier names shift, control,
      lock, meta, mod1, mod2, mod3, mod4, or mod5 (which may be abbreviated
      as s, c, l, m, m1, m2, m3, m4, m5, respectively) separated by a
      vertical bar (|).  Similarly, the context is any combination of
      window, title, icon, root, frame, virtual, desktop, door, iconmgr,
      their first letters (iconmgr abbreviation is m, door has no
      abbreviation), or all, separated by a vertical bar.  It is rumored
      that window class names will also work.  The function is any of the f.
      keywords described below.  For example, the default startup file
      contains the following bindings:
           Button1 =       : root          : f.menu "VTWM Windows"
           Button1 = m     : window | icon : f.function "move-or-lower"
           Button2 = m     : window | icon : f.iconify
           Button3 = m     : window | icon : f.function "move-or-raise"
           Button1 =       : title         : f.function "move-or-raise"
           Button2 =       : title         : f.raiselower
           Button1 =       : icon          : f.function "move-or-iconify"
           Button2 =       : icon          : f.iconify
           Button1 =       : iconmgr       : f.iconify
           Button2 =       : iconmgr       : f.iconify

      A user who wanted to be able to manipulate windows from the keyboard
      could use the following bindings:
           "F1"            =       : all           : f.iconify
           "F2"            =       : all           : f.raiselower

      Note, however, that using all for button or key bindings is almost
      always a bad idea, since it prevents all applications from receiving
      those events; this can cripple text and graphics editors that
      otherwise expect to see those buttons or keys.

      vtwm provides many more window manipulation primitives than can be
      conveniently stored in a titlebar, menu, or set of key bindings.
      Although a small set of defaults are supplied (unless either
      NoDefaults, NoDefaultMouseOrKeyboardBindings, or NoDefaultTitleButtons
      is specified), most users will want to have their most common
      operations bound to key and button strokes.  To do this, vtwm
      associates names with each of the primitives and provides user-defined
      functions for building higher level primitives and menus for
      interactively selecting among groups of functions.

      User-defined functions contain the name by which they are referenced
      in calls to f.function and a list of other functions to execute.  For
      example:
           Function "move-or-lower"        { f.move f.deltastop f.lower }
           Function "move-or-raise"        { f.move f.deltastop f.raise }
           Function "move-or-iconify"      { f.move f.deltastop f.iconify }
           Function "restore-colormap"     { f.colormap "default" f.lower }

      The function name must be used in f.function exactly as it appears in
      the function specification.

      VTWM PROFILE.  If a function called "VTWM Profile" is defined within
      the startup file, that function will be executed upon startup or
      restarting of the window manager.  For example:
           AutoPan 25
                   .
                   .
           Function "VTWM Profile"
           {
                   .
                   .
               f.autopan
                   .
                   .
           }

      have a value unless AutoPan is set in the startup file; see f.autopan
      below), in case you want to turn it on sometime later.

      In the descriptions below, if the function is said to operate on the
      selected window, but is invoked from a root menu, the cursor will be
      changed to the Select cursor and the next window to receive a button
      press will be chosen:

      ! string
              This is an abbreviation for f.exec string.

      ^ string (OBSOLETE --- use a clipboard client)
              This is an abbreviation for f.cut string.

      f.autopan
              If autopan wasn't configured in your .vtwmrc file, this does
              nothing. If, however, it was configured, this toggles the
              current autopan state. The reason for this command is that
              autopan is sometimes nice to have, but it interferes with
              using sticky windows that are near the edge of the screen.
              With this command, you get the best of both worlds.

      f.autoraise
              This function toggles whether or not the selected window is
              raised whenever entered by the pointer.  See the description
              of the variable AutoRaise.

      f.backiconmgr
              This function warps the pointer to the previous column in the
              current icon manager, wrapping back to the previous row if
              necessary.

      f.beep  This function sounds the keyboard bell.

      f.bottomzoom
              This function is similar to the f.fullzoom function, but
              resizes the window to fill only the bottom half of the screen.

      f.circledown
              This function lowers the top-most window that occludes another
              window.

      f.circleup
              This function raises the bottom-most window that is occluded
              by another window.

      f.colormap string
              This function rotates the colormaps (obtained from the
              WM_COLORMAP_WINDOWS property on the window) that vtwm will
              display when the pointer is in this window.  The argument

              string may have one of the following values: "next", "prev",
              and "default".  It should be noted here that in general, the
              installed colormap is determined by keyboard focus.  A pointer
              driven keyboard focus will install a private colormap upon
              entry of the window owning the colormap.  Using the click to
              type model, private colormaps will not be installed until the
              user presses a mouse button on the target window.

      f.cut string (OBSOLETE --- use a clipboard client)
              This function places the specified string (followed by a
              newline character) into the root window property CUT_BUFFER0.

      f.cutfile (OBSOLETE --- use a clipboard client)
              This function reads the file indicated by the contents of the
              CUT_BUFFER0 window property and replaces the cut buffer.

      f.deiconify
              This function deiconifies the selected window.  If the window
              is not an icon, this function does nothing.

      f.delete
              This function sends the WM_DELETE_WINDOW message to the
              selected window if the client application has requested it
              through the WM_PROTOCOLS window property.  The application is
              supposed to respond to the message by removing the indicated
              window.  If the window has not requested WM_DELETE_WINDOW
              messages, the keyboard bell will be rung indicating that the
              user should choose an alternative method.  Note this is very
              different from f.destroy.  The intent here is to delete a
              single window,  not necessarily the entire application.

      f.deletedoor
              This function deletes a door. ... maybe some X-guru can check
              all memory allocated to a door is released when deleting a
              door ...

      f.deltastop
              This function allows a user-defined function to be aborted if
              the pointer has been moved more than MoveDelta pixels.  See
              the example definition given for Function "move-or-raise" at
              the beginning of the section.

      f.destroy
              This function instructs the X server to close the display
              connection of the client that created the selected window.
              This should only be used as a last resort for shutting down
              runaway clients.  See also f.delete.

              This action sometimes leaves a runaway process that consumes
              CPU cycles; you should always try to use the applications own
              quit function, rather than this one.

              This function warps the pointer to the next row in the current
              icon manger, wrapping to the beginning of the next column if
              necessary.

      f.enterdoor
              This function activates this door.  Typically one binds:
              Button1 =   : door  : f.enterdoor
              Button2 =   : door  : f.enterdoor
              Button3 =   : door  : f.enterdoor

      f.exec string
              This function passes the argument string to /bin/sh for
              execution.  In multiscreen mode, if string starts a new X
              client without giving a display argument, the client will
              appear on the screen from which this function was invoked.

      f.file string (OBSOLETE --- use a clipboard client)
              This function assumes string is a file name.  This file is
              read into the window server's cut buffer.

      f.focus This function toggles the keyboard focus of the server to the
              selected window, changing the focus rule from pointer-driven
              if necessary.  If the selected window already was focused,
              this function executes an f.unfocus.

      f.forcemove
              This function is like f.move except that it ignores the
              DontMoveOff variable.

      f.forwiconmgr
              This function warps the pointer to the next column in the
              current icon manager, wrapping to the beginning of the next
              row if necessary.

      f.fullzoom
              This function resizes the selected window to the full size of
              the display or else restores the original size if the window
              was already zoomed.

      f.function string
              This function executes the user-defined function whose name is
              specified by the argument string.

      f.hbzoom

              This function unmaps the current icon manager when selected
              from a client window, and unmaps all icon managers when
              selected from the root window.

      f.horizoom
              This variable is similar to the f.zoom function except that
              the selected window is resized to the full width of the
              display.

      f.htzoom
              This function is a synonym for f.topzoom.

      f.hzoom This function is a synonym for f.horizoom.

      f.iconify
              This function iconifies or deiconifies the selected window or
              icon, respectively.

      f.identify
              This function displays a summary of the name and geometry of
              the selected window.  Clicking the pointer or pressing a key
              in the window will dismiss it.  If the function is invoked on
              a desktop representation of a window, the real window which is
              represented will be identified.

      f.lefticonmgr
              This function similar to f.backiconmgr except that wrapping
              does not change rows.

      f.leftzoom
              This variable is similar to the f.bottomzoom function but
              causes the selected window is only resized to the left half of
              the display.

      f.lower This function lowers the selected window.

      f.menu string
              This function invokes the menu specified by the argument
              string.  Cascaded menus may be built by nesting calls to
              f.menu.

      f.move  This function drags an outline of the selected window (or the
              window itself if the OpaqueMove variable is set) until the
              invoking pointer button is released.  Double clicking within
              the number of milliseconds given by ConstrainedMoveTime warps
              the pointer to the center of the window and constrains the
              move to be either horizontal or vertical depending on which
              grid line is crossed. To abort a move, press another button
              before releasing the first button.

      f.movescreen
              Moves a window (or possibly the real screen) inside the
              desktop display.  By default, the bindings using the desktop
              context are defined as:
              Button1 = : desktop : f.movescreen
              Button2 = : desktop : f.movescreen

              This is useful if you want to reset the default keyboard and
              mouse bindings via NoDefaultMouseOrKeyboardBindings and use
              some of your own for the virtual desktop, e.g.:
              NoDefaultMouseOrKeyboardBindings

              This function is not useful under any context other than
              "desktop".

      f.nail  This function nails or unnails the specified window onto the
              real screen-the current value of this property is toggled on
              the specified window.

      f.nailedabove
              This function toggles the setting of the NailedAbove variable.

      f.namedoor
              This function, bound to the door context, pastes a name from
              CUT_BUFFER0 into the selected door (see the BINDINGS section
              for details).

      f.newdoor
              This function creates a new door with it's destination and
              name set to the real screen's current position in the virtual
              desktop.

      f.nexticonmgr
              This function warps the pointer to the next icon manager
              containing any windows on the current or any succeeding
              screen.

      f.nop   This function does nothing and is typically used with the

      f.quit  This function causes vtwm to restore the window's borders and
              exit.  If vtwm is the last client invoked from xdm, this will
              result in a server reset, and the user's session will be

              such as xbiff(1), as the last application in their .xinitrc or
              .xsession file, letting the window manager start earlier, and
              run in the background.  This allows changing window managers
              without logging out, and also makes it much less likely that a
              session will be abruptly terminated by a bug in a complex
              program like a window manager.  The one drawback to this
              approach is that f.quit then no longer terminates the session:
              you need to use f.delete or f.destroy on that last application
              to logout.

      f.raise This function raises the selected window.

      f.raiselower
              This function raises the selected window to the top of the
              stacking order if it is occluded by any windows, otherwise the
              window will be lowered.

      f.refresh
              This function causes all windows to be refreshed.

      f.resetdesktop
              This function moves the real display to (0,0)

      f.resize
              This function displays an outline of the selected window.
              Crossing a border (or setting AutoRelativeResize) will cause
              the outline to begin to rubber band until the invoking button
              is released.  To abort the resize, press another button before
              releasing the first button.  Note that the window itself is
              manipulated if the OpaqueResize variable is not set.

              This function kills and restarts vtwm. See also f.startwm.

      f.righticonmgr
              This function is similar to f.nexticonmgr except that wrapping
              does not change rows.

      f.rightzoom
              This variable is similar to the f.bottomzoom function except
              that the selected window is only resized to the right half of
              the display.

      f.ring  Selects a window and adds it to the WarpRing, or removes it if
              it was already in the ring. This command makes f.warpring much
              more useful, by making its configuration dynamic.

      f.saveyourself
              This function sends a WM_SAVEYOURSELF message to the selected
              window if it has requested the message in its WM_PROTOCOLS
              window property.  Clients that accept this message are
              supposed to checkpoint all state associated with the window
              and update the WM_COMMAND property as specified in the ICCCM.
              If the selected window has not selected for this message, the
              keyboard bell will be rung.

      f.separator
              Valid only in menus. The effect is to add a line separator
              between the previous and the following entry. The name
              selector part in the menu is not used (but must be present).

      f.setrealscreen geomstr
              This function sets the real screen to the virtual coordinates
              specified.  The geomstr is a quoted string containing a
              standard geometry specification.

      f.showdesktopdisplay
              This function maps the desktop display.

      f.showiconmgr
              This function maps the current icon manager when selected from
              a client window, and maps all icon managers when selected from
              the root window.

      f.snap  This function snaps the real screen to a grid defined on
              virtual space with PanDistanceX and PanDistanceY increments.

              This function sorts the entries in the current icon manager
              alphabetically.  See the variable SortIconManager.

      f.sounds
              This function toggles the playing of sounds. It's a "mute"
              function.

      f.squeezecenter
              Selects a window and makes its title appear as though you had
              configured it as SqueezeTitle center 0 0; makes squeezed
              titles much more useful because their configuration is
              dynamic.

      f.squeezeleft
              Selects a window and makes its title appear as though you had
              configured it as SqueezeTitle left 0 0; makes squeezed titles
              much more useful because their configuration is dynamic.

              much more useful because their configuration is dynamic.

      f.startwm commandline
              This function kills vtwm, and starts up the window manager
              specified by commandline. Note that commandline accepts up to
              eight options for the command (as counted by whitespace), and
              that no environment variables nor a trailing ampersand should
              be used. See also f.restart.

              the display.

      f.twmrc Synonymous with f.restart.  Historically, this function was
              intended to cause the startup customization file to be re-
              read.

      f.unfocus
              This function resets the focus back to pointer-driven.  This
              should be used when a focused window is no longer desired.

      f.upiconmgr
              This function warps the pointer to the previous row in the
              current icon manager, wrapping to the last row in the same
              column if necessary.

      f.version
              This function causes the vtwm version window to be displayed.
              This window will be displayed until a pointer button is
              pressed or the pointer is moved from one window to another.

      f.warpclassnext string

      f.warpclassprev string
              These functions warp the pointer to the next or previous
              window in the specified class indicated by the argument
              string.  If string is "VTWM", only icon managers, doors, and
              the Virtual Desktop window are considered.  If string empty
              (i.e., ""), the class of the window with focus is used.  If
              the window is iconified, it will be deiconified if the
              variable WarpUnmapped is set or else ignored.

      f.warpring string

              or class that matches string.  If the window is iconified, it
              will be deiconified if the variable WarpUnmapped is set or
              else ignored.

      f.warptoiconmgr string

              associated with the window containing the pointer in the icon
              manager specified by the argument string.  If string is empty
              (i.e., ""), the current icon manager is chosen.  If the window

              the variable WarpUnmapped is set or else ignored.

      f.warptoscreen string
              This function warps the pointer to the screen specified by the
              argument string.  String may be a number (e.g., "0" or "1"),
              the word "next" (indicating the current screen plus 1,
              skipping over any unmanaged screens), the word "back"
              (indicating the current screen minus 1, skipping over any
              unmanaged screens), or the word "prev" (indicating the last
              screen visited.

                               Release 5.4.6b



      Functions may be grouped and interactively selected using pop-up (when
      bound to a pointer button) or pull-down (when associated with a
      titlebutton) menus.  Each menu specification contains the name of the
      menu as it will be referred to by f.menu, optional default foreground
      and background colors, the list of item names and the functions they
      should invoke, and optional foreground and background colors for
      individual items:
           Menu "menuname" [ ("deffore":"defback") ]
           {
                   string1   [ ("fore1":"back1")]        function1
                   string2   [ ("fore2":"back2")]        function2
                           .
                           .
                           .
                   stringN   [ ("foreN":"backN")]        functionN
           }

      The menuname is case-sensitive.  The optional deffore and defback
      arguments specify the foreground and background colors used on a color
      display to highlight menu entries.  The string portion of each menu
      entry will be the text which will appear in the menu.  The optional
      fore and back arguments specify the foreground and background colors
      of the menu entry when the pointer is not in the entry.  These colors
      will only be used on a color display.  The default is to use the
      colors specified by the MenuForeground and MenuBackground variables.
      The function portion of the menu entry is one of the functions,
      including any user-defined functions, or additional menus.

      There is a special menu named VTWM Windows which contains the names of
      all of the client and vtwm-supplied windows.  Selecting an entry will
      cause the WindowFunction to be executed on that window.  If
      WindowFunction hasn't been set, the window will be deiconified and
      raised.  This menu uses the same colors as the little windows in the
      panner.  This feature still honors the traditional TwmWindows menu
      name of yore.

 ICONS
      vtwm supports several different ways of manipulating iconified
      windows.  The common image-and-text style may be laid out by hand or
      automatically arranged as described by the IconRegion variable.  In
      addition, a terse grid of icon names, called an icon manager, provides
      a more efficient use of screen space as well as the ability to
      navigate among windows from the keyboard.

      An icon manager is a window that contains names of selected or all
      windows currently on the display.  In addition to the window name, a
      small button using the default iconify symbol will be displayed to the
      left of the name when the window is iconified.  By default, clicking
      on an entry in the icon manager performs f.iconify.  To change the
      actions taken in the icon manager, use the iconmgr context when
      specifying button and keyboard bindings.

                               Release 5.4.6b



      Moving the pointer into the icon manager also directs keyboard focus
      to the indicated window when NoIconManagerFocus is not set (setting
      the focus explicitly or else sending synthetic events if NoTitleFocus
      is set).  Using the f.upiconmgr, f.downiconmgr f.lefticonmgr, and
      f.righticonmgr functions, the input focus can be changed between
      windows directly from the keyboard.

 IMAGE FORMATS
      vtwm supports a single image file format by default, the X Window
      System bitmap (files typically carrying an extension of ".xbm"), for
      two-color images.

      However, when built with the XPM library, vtwm will also support the X
      Window System pixmap (files typically carrying an extension of
      ".xpm"), for full-color images, and the transparency extension of
      these will be honored when present.

      The two can be freely mixed within the variables that use them: Icons,
      RealScreenPixmap, TitleHighlight, VirtualBackgroundPixmap, and the
      image specification in titlebutton bindings.

      The root window can be decorated with whatever image file format that
      is supported by whatever X Window System utilities and applications
      you may have installed (xloadimage(1), xsetroot(1), xv(1), etc.).

 WILDCARDS
      vtwm supports "wildcarding" when matching windows against a variable's
      win-list. By default, the question mark ('?') represents any single
      character, the asterisk ('*') represents any zero or more characters,
      and brackets ('[' and ']') represent any characters listed within
      them. The backslash ('\') "escapes" any one character, allowing these
      reserved characters to be used literally.

      vtwm can support a richer method of character substitution, called
      regular expressions, or "RE"s. If vtwm is built with REs, many more
      "wildcard" rules are added. A description of REs is beyond the scope
      of this document; see the re_format(7) or egrep(1) man pages.

      vtwm distinguishes REs from strings by enclosing them in forward
      slashes ('/'). The two may be freely mixed; changing the example in
      the VARIABLES section to:
           AutoRaise
           {
                   "emacs"
                   "VTWM*"
                   /x.*clock/ # was "x*clock"
                   "Xmh"
                   "XTerm"
           }
      accomplishes the same thing. This is but a simple example of RE usage,
      and as such doesn't demonstrate or leverage their capabilities.

 SIGNALS
      It is possible to issue a f.restart via a UNIX signal, to ease
      debugging of vtwm resource files.  To do this, send a SIGUSR1 to the
      vtwm process ID (written to $HOME/vtwm.pid).  See kill(1) or slay(1).

 BUGS
      There are precious few safeguards against binding functions to objects
      inappropriately, especially where the virtual desktop is concerned.

      Double clicking very fast to get the constrained move function will
      sometimes cause the window to move, even though the pointer is not
      moved.

      It is possible to "lose" windows in the virtual desktop by placing
      them in a large desktop area, then shrinking the desktop so as to
      remove them from view. They are still there, of course, but are
      unreachable until the desktop is grown sufficiently large again.

      See the BUGS file in the distribution for others.
