NAME

       fvwm1 - F(?) Virtual Window Manager for X11, version 1.x

SYNOPSIS

       fvwm1 [ options ]

DESCRIPTION

       Fvwm is a window manager for X11. It is a derivative of twm, redesigned to minimize memory
       consumption, provide a 3-D look to window frames, and provide a  simple  virtual  desktop.
       Memory  consumption  is estimated at about one-half to one-third the memory consumption of
       twm, due primarily to a redesign of twm's method of storing mouse bindings.  In  addition,
       many of the configurable options of twm have been removed.

       The  name  "FVWM" used to stand for something, but I forgot what. (Feeble, famous, foobar?
       It doesn't really matter, this is an acronym based society anyway.)

STATUS OF THIS SOFTWARE

       Since the release of FVWM 2.2 in March 1999, this release is officially deprecated and  no
       longer  supported.   Please  do  not  report  any bugs in this software.  Also, for Debian
       users, the module manpages for this release of FVWM will be found as FvwmAudio1(1x) etc.

SPECIAL NOTE FOR XFREE86 USERS

       XFree86 provides  a  virtual  screen  whose  operation  can  be  confusing  when  used  in
       conjunction  with  fvwm.  With  XFree86  all  windows  which  appear on the virtual screen
       actually get drawn into video memory (whether or not they appear on the physical  screen),
       so the virtual screen size is limited by available video memory.

       With fvwm's virtual desktop, windows which do not appear on the screen do not actually get
       drawn into video RAM. The size of the virtual desktop is limited to about 32,000 by 32,000
       pixels,  but  it  is probably impractical to use a virtual desktop more than about 5 times
       the visible screen in each direction.  Note that memory usage is a function of the  number
       of windows which exist - the size of the desktop makes no difference.

       When  becoming  familiar  with  fvwm  it is recommended that you disable XFree86's virtual
       screen by setting the virtual screen size to the physical screen size.  After  you  become
       familiar with fvwm you may want to re-enable XFree86's virtual screen.

       CONNECTION WITH THE USE OR PERFORMANCE OF THIS SOFTWARE.

ANATOMY OF A WINDOW

       Fvwm  puts  a decorative border around most windows. This border consists of a bar on each
       side and a small "L" shaped section on each corner.  There is an additional top bar called
       the  title  bar which is used to display the name of the window. In addition, there are up
       to 10 title-bar buttons.  The top, side, and bottom bars are  collectively  known  as  the
       side-bars.  The corner pieces are called the frame.

       Unless  the  standard defaults files are modified, pressing mouse button 1 in the title or
       side-bars will begin a move operation on the window. Pressing button 1 in the corner frame
       pieces  will  begin a resize operation. Pressing button 2 anywhere in the border brings up
       an extensive list of window operations.

       Up to ten title-bar buttons may exist.  Their  use  is  completely  user  definable.   The
       default configuration has a title-bar button on each side of the title-bar. The one on the
       left is used to bring up a list of window options, regardless of  which  mouse  button  is
       used. The one on the right is used to iconify the window.  The number of title-bar buttons
       used depends on which ones have mouse actions bound  to  them.  See  the  section  on  the
       "Mouse" configuration parameter below.

THE VIRTUAL DESKTOP

       Fvwm  provides  multiple  virtual desktops for users who wish to use them. The screen is a
       viewport onto a desktop which may be larger than the screen. Several distinct desktops can
       be  accessed  (concept: one desktop for each project, or one desktop for each application,
       when view applications are distinct).  Since each desktop can be larger than the  physical
       screen,  windows  which  are larger than the screen or large groups of related windows can
       easily be viewed.

       The size of the virtual desktops can be specified at start-up.  All virtual desktops  must
       be  the  same  size.  The  total number of distinct desktops need not be specified, but is
       limited to approximately 4 billion total. All  windows  on  the  current  desktop  can  be
       displayed  in  a  Pager, a miniature view of the current desktop. Windows which are not on
       the current desktop can be  listed,  along  with  their  geometries,  in  a  window  list,
       accessible as a pop-up menu.

       "Sticky"  windows  are  windows  which  transcend  the virtual desktop by "Sticking to the
       screen's glass." They always stay put on the screen.  This is convenient for  things  like
       clocks and xbiff's, so you only need to run one such gadget and it always stays with you.

       Window geometries are specified relative to the current viewport. That is:
       xterm -geometry +0+0
       will always show up in the upper-left hand corner of the visible portion of the screen. It
       is permissible to specify geometries which place windows on the virtual desktop,  but  off
       the  screen.  For  example,  if the visible screen is 1000 by 1000 pixels, and the desktop
       size is 3x3, and the current viewport is at the upper left hand  corner  of  the  desktop,
       then invoking:
       xterm -geometry +1000+1000
       will  place  the  window  just off of the lower right hand corner of the screen. It can be
       found by moving the mouse to the lower right hand corner of the screen and waiting for  it
       to  scroll  into  view.  There is currently no way to cause a window to map onto a desktop
       other than the currently active desk.

       A geometry specified as something like:
       xterm -geometry -5-5
       will generally place the window's lower right hand corner 5 pixels from  the  lower  right
       corner  of  the  visible  portion  of  the  screen.  Not  all  applications support window
       geometries with negative offsets.

       Some applications, like xterm and xfontsel, allow the user to specify the start-up desk on
       the command line:
       xterm -xrm "*Desk:1"
       will  start  an  xterm  on  desk  number  1.  Not all applications understand this option,
       however.

INITIALIZATION

       During initialization, fvwm will search for a configuration file which describes  key  and
       button  bindings,  and  a  few  other  things. The format of these files will be described
       later. First, fvwm will search for a file named  .fvwmrc  in  the  users  home  directory.
       Failing  that,  it  will look for /etc/X11/fvwm/system.fvwmrc for system-wide defaults. If
       that file is not found, fvwm will exit.

       Fvwm will set two environment variables which will be inherited by its children. These are
       $DISPLAY which describes the display on which fvwm is running. $DISPLAY may be unix:0.0 or
       :0.0, which doesn't work  too  well  when  passed  through  rsh  to  another  machine,  so
       $HOSTDISPLAY  will  also  be  set and will use a network-ready description of the display.
       $HOSTDISPLAY will always use the TCP/IP transport protocol (even for a  local  connection)
       so $DISPLAY should be used for local connections, as it may use Unix-domain sockets, which
       are faster.

SHAPED WINDOWS

       If you typically use shaped windows such as xeyes or oclock, you have several options. You
       can make them all undecorated (NoBorder oclock and NoTitle oclock, for example) or you can
       use the default configuration and leave them decorated, in which case a decorative  border
       and a solid-color backdrop are shown. Alternately, you can compile in the SHAPE extensions
       by changing a flag in the Makefile, in which case  you  get  the  shaped  window  with  no
       backdrop,  and  a title bar floats above the window. The shaped window extensions increase
       the window manager's memory consumption by about 60 Kbytes  when  no  shaped  windows  are
       present but have little effect when shaped windows are present.

ICONS

       The  basic  Fvwm  configuration  uses  monochrome  bitmap  icons,  similar  to twm. If XPM
       extensions are compiled in, then color icons similar to ctwm, MS-Windows, or the Macintosh
       icons  can  be  used.  In  order  to  use  these options you will need the XPM package, as
       described in the Makefile.noImake and the Imakefile.

       If both the SHAPE and XPM options are compiled in you will get shaped color  icons,  which
       are very spiffy.

MODULES

       A  module  is  a  separate  program  which  runs  as a separate Unix process but transmits
       commands to fvwm to execute. Future releases are expected to provide  a  means  for  these
       modules  to extract window information from fvwm.  Users can write their own modules to do
       any weird or bizarre manipulations without affecting the integrity of fvwm itself.

       Modules MUST be spawned by fvwm so that it can set up two pipes for fvwm and the module to
       communicate  with.  The  pipes  will already be open for the module when it starts and the
       file descriptors for the pipes are provided as command line arguments.

       Modules can be spawned during fvwm initialization via the Module option, or  at  any  time
       during  the X session by use of the Module built-in. Modules can exist for the duration of
       the X session, or can perform a single task and exit. If the module is still  active  when
       fvwm  is  told to quit, then fvwm will close the communication pipes and wait to receive a
       SIGCHLD from the module, indicating that it has detected the pipe closure and has  exited.
       If  modules  fail to detect the pipe closure fvwm will exit after approximately 30 seconds
       anyway. The number of  simultaneously  executing  modules  is  limited  by  the  operating
       system's maximum number of simultaneously open files, usually between 60 and 256.

       Modules  simply  transmit text commands to the fvwm built-in command engine. Text commands
       are formatted just as in the case of a mouse binding in the .fvwmrc  setup  file.  Certain
       auxiliary  information  is  also  transmitted,  as  in  the  sample  module GoodStuff. The
       GoodStuff module is documented in its own man page.

ICCCM COMPLIANCE

       Fvwm attempts to be ICCCM 1.1 compliant. As of  this  (1.20l)  colormap  handling  is  not
       completely  ICCCM  compliant.  In  addition,  ICCCM  states that it should be possible for
       applications to receive ANY keystroke, which is not consistent with the keyboard  shortcut
       approach used in fvwm and most other window managers.

M4 PREPROCESSING

       If  fvwm  is  compiled  with  the M4 option, fvwm uses m4(1) to preprocess its setup files
       before parsing. This way you can use m4 macros to perform  operations  at  runtime.   This
       makes it very easy to work with different displays with different characteristics.

       For  example,  depending on your mood, you might want different color schemes.  One way of
       doing this is by using the -m4opt to specify your mood.   For  a  sunny  mood  use  -m4opt
       -DSunny; for a dark mood use -m4opt -DDark.  Your .fvwmrc file might then contain:
       ifdef(`Sunny',`
       StdForeColor        Black
       StdBackColor        LightSkyBlue
       HiForeColor         yellow
       HiBackColor         PeachPuff1
       PagerBackColor      BlanchedAlmond ')

       ifdef(`Dark',`
       StdForeColor        Black
       StdBackColor        #60a0c0
       HiForeColor         black
       HiBackColor         #c06077
       PagerBackColor      #5c54c0
       PagerForeColor      orchid
       StickyForeColor          Black
       StickyBackColor          #60c0a0 ')

       The following m4 symbols are predefined by fvwm:

       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.)

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

       CLIENTHOST              The machine that is running the clients.

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

       FVWMDIR                 This is set to the path where the modules were  configured  to  be
                               installed.

       FVWM_VERSION            This is a string containing the version of fvwm.

       HEIGHT                  The height of your display in pixels.

       HOME                    The user's home directory.  Obtained from the environment.

       HOSTNAME                The  canonical hostname running the clients (ie. a fully-qualified
                               version of CLIENTHOST).

       OPTIONS                 This is a string of compile time options  used.   Each  option  is
                               separated from the other by a space.

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

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

       REVISION                The X minor protocol revision.  As seen by ProtocolRevision(3).

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

       TWM_TYPE                Tells which twm offshoot is running.  It will always be set to the
                               string "fvwm" in this program.   This  is  useful  for  protecting
                               parts  of your .twmrc file that fvwm proper won't understand (like
                               WorkSpaces) so that it is still usable with other twm programs.

       USER                    The name of the user  running  the  program.   Obtained  from  the
                               environment.

       VENDOR                  The vendor of your X server.  For example: MIT X Consortium.

       VERSION                 The X major protocol version.  As seen by ProtocolVersion(3).

       WIDTH                   The width 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.

       You  may  well find that if you research the m4(1) manual well and understand the power of
       m4, this will be a very useful and powerful tool.  But if you use any of the symbols which
       are predefined by m4, you are in severe danger!  For example, Sun's m4 predefines include,
       so if you use that name in your .fvwmrc, you are out of luck.   The  correct  solution  to
       this problem is to put a set of quotes around the troublesome word:  `include'.

       To  help  alleviate  this  problem,  the  following  options may be useful.  To change the
       quoting characters used by m4, use the options -m4-squote  and  -m4-equote.   Be  sure  to
       specify  both  options otherwise m4 will be confused.  When these are given, a changequote
       macro is given before the users fvwmrc file is processed.

       NOTE: Some versions of m4 are broken with  respect  to  changing  quoting  characters  and
       included  files.   When  the  quoting  strings  are  longer  than one character, the macro
       "include(<<file>>)", where "<<" and  ">>"  are  the  quoting  characters,  contains  extra
       characters around the contents of the included file.  This will confuse fvwm.  SunOS 4.1.3
       is known to have this problem.

       If you are using GNU m4 an additional option is available.  By specifying -m4-prefix  when
       starting  fvwm,  m4  is  instructed  to prefix all builtin macros with m4_.  Thus, include
       becomes m4_include.

       The availability of the m4 preprocessing is subject to the compilation define M4.

OPTIONS

       These are the command line options that are recoginzed by fvwm:

       -f config_file
              Causes fvwm to use config_file in the user's home directory instead of  .fvwmrc  as
              the window manager configuration file.

       -debug Puts  X transactions in synchronous mode, which dramatically slows things down, but
              guarantees that fvwm's internal error messages are correct.

       -d displayname
              Manage the display called "displayname" instead  of  the  name  obtained  from  the
              environment variable $DISPLAY.

       -s     On  a  multi-screen  display,  run  fvwm  only  on the screen named in the $DISPLAY
              environment variable or provided through the -d option. Normally, fvwm will attempt
              to start up on all screens of a multi-screen display.

       -version
              Print the version of fvwm to stderr.

       The following options are available only if fvwm is compiled with the M4 option.

       -no-m4 Do  not use m4 to preprocess the .fvwmrc.  The default is to preprocess the startup
              file using m4(1).

       -m4-prefix
              If GNU m4 is available, cause m4 to prefix all builtin commands with m4_.

       -m4opt option
              Pass this option to m4.  The option can be any string of characters without spaces.
              This  option  can occur multiple times.  If GNU m4 is available, DO NOT pass the -P
              option here.  Use -m4-prefix instead.

       -m4-squote string
              Use this given string as the starting quote  characters.   You  must  also  specify
              -m4-equote.

       -m4-equote string
              Use  this  given  string  as  the  ending  quote characters.  You must also specify
              -m4-squote.

       -m4prog path
              Use path as the location of the desired m4 processor.  By default, m4prog is set to
              "m4" which must exist somewhere on the user's path.  This option allows the user to
              explicitly choose the version of m4 to use.

CONFIGURATION FILES

       The configuration file is used to describe mouse and button bindings, colors, the  virtual
       display  size,  and related items. This section describes the configuration options. Lines
       beginning with '#' will be ignored by fvwm.  Lines  starting  with  '*'  are  expected  to
       contain  module  configuration  commands  (rather  than  configuration  commands  for fvwm
       itself).

       AppsBackingStore
              Causes application windows to request backing store. This  option  compromises  the
              ICCCM compliance of the window manager. While this option can speed things up in an
              X-terminal, where redraws of windows are expensive, it may not help much on regular
              workstations.

       AutoRaise delay
              Enables  auto-raising  of  windows  and  specifies the time delay (in milliseconds)
              between when a window acquires the input focus and when it is automatically raised.
              This  option  works  in focus-follows-mouse mode, and in click-to-focus mode if the
              focus is changed by clicking in the application  window  instead  of  a  decoration
              window.  In  click-to-focus  mode,  you can suppress the raise-on-focus behavior by
              specifying a negative delay value.

       BackingStore
              Causes  fvwm  decorations  to  request  backing  store.  See  the   discussion   on
              AppsBackingStore.

       BoundaryWidth Width
              Changes  the  boundary  width  on  decorated  windows  to the specified value.  The
              default is 6 pixels.

              The  Style  command  provides  another  (more  general)   method   for   specifying
              BoundaryWidth.

       ButtonStyle button# WidthxHeight
              Defines the rectangular decoration shape to be used in a title-bar button.  button#
              is the title-bar button number, and is between 0 and 9.  A description of title-bar
              button numbers is given in the Mouse section below.  Width is the percentage of the
              full button width which is to be used. Height is the percentage of the full  height
              to be used. Negative numbers cause the shading to be inverted.

              And that's not all! If you use a line like:
              ButtonStyle : 2 4 50x30@1 70x70@0 30x70@0 50x30@1
              then  the  button 2 decoration will use a 4-point pattern consisting of a line from
              (x=50,y=30) to (70,70) in the shadow color (@0), and then to (30,70) in the  shadow
              color,  and  finally to (50,30) in the highlight color (@1). Is that too confusing?
              See the sample system.fvwmrc.

       CenterOnCirculate
              When circulating, the desktop page containing  the  window  which  the  pointer  is
              moving  to  is  automatically  selected. If CenterOnCirculate is selected then fvwm
              will do its best to center the target window in the desktop viewport,  rather  than
              just lining up to the closest page.

       CirculateSkip windowname
              Causes  windows with the indicated name to be skipped over when the circulate-up or
              circulate-down functions are invoked. windowname can be  a  window's  name  or  its
              class.

              The   Style   command   provides  another  (more  general)  method  for  specifying
              CirculateSkip.

       CirculateSkipIcons
              Causes circulate and warp operations to skip over iconified windows.

       ClickTime delay
              Specifies the maximum delay (in milliseconds) between a button press and  a  button
              release for the Function built-in to consider the action a mouse click. The default
              delay is 150 milliseconds.

       ClickToFocus
              Normally keyboard input goes to the window the mouse pointer is in. If this  option
              is set the keyboard input stays with one window until the mouse is clicked with the
              pointer positioned in a new window.

       Cursor  cursor_num cursor_type
              This provides a very awkward way of changing cursor styles. Cursor_num tells  which
              cursor you are changing, and is a number between 0 and 12, as follows:

                 0 POSITION     - used when initially placing windows.
                 1 TITLE        - used in a window title-bar.
                 2 DEFAULT      - used in windows that don't set their cursor.
                 3 SYS          - used in one of the title-bar buttons.
                 4 MOVE         - used when moving or resizing windows.
                 5 WAIT         - used during an EXEC builtin command.
                 6 MENU         - used in menus.
                 7 SELECT       - used for various builtin commands such as iconify.
                 8 DESTROY      - used for DESTROY and DELETE built-ins.
                 9 TOP          - used in the top side-bar of a window.
                10 RIGHT        - used in the right side-bar of a window.
                11 BOTTOM       - used in the bottom side-bar of a window.
                12 LEFT         - used in the left side-bar of a window.
                13 TOP_LEFT     - used in the top left corner of a window.
                14 TOP_RIGHT    - used in the top right corner of a window.
                15 BOTTOM_LEFT  - used in the bottom left corner of a window.
                16 BOTTOM_RIGHT - used in the bottom right corner of a window.

              The  cursor_type  argument  is  a  number  which tells the cursor shape to use. The
              available numbers can be found in /usr/include/X11/cursorfont.h and  are  currently
              even numbers between 0 and 152. At the current time, the following cursor types are
              available:

                0   X_cursor                  2   arrow
                4   based_arrow_down          6   based_arrow_up

                152 xterm

       DecorateTransients
              Causes transient windows, which are normally left  undecorated,  to  be  given  the
              usual fvwm decorations. Note that some pop-up windows, such as the xterm menus, are
              not managed by the window manager and still do not receive decorations.

       DeskTopScale Scale
              Defines the virtual desktop scale with respect to the screen.

       DeskTopSize HorizontalxVertical
              Defines the virtual desktop size in units of the physical screen size.

       DontMoveOff
              Prevents windows from being moved off or initially placed off of  the  desktop.   A
              few  programs  will  not  work  correctly  if  you use this option. This only keeps
              windows from being completely lost off the edge  of  the  desktop.  It  insists  on
              keeping  16  pixels  on  the desktop but doesn't care a bit about keeping the whole
              window on the desk. See EdgeResistance if you don't like having  windows  partially
              off the screen.

       EdgeResistance scrolling moving
              Tells how hard it should be to change the desktop viewport by moving the mouse over
              the edge of the screen and how hard it should be to move a window over the edge  of
              the screen.

              The  first  parameter  tells  how milliseconds the pointer must spend on the screen
              edge before fvwm will move the viewport.  This  is  intended  for  people  who  use
              "EdgeScroll  100  100"  but  find  themselves accidentally flipping pages when they
              don't want to.

              The second parameter tells how many pixels over the edge of the screen  a  window's
              edge must move before it actually moves partially off the screen.

              Note  that,  with  "EdgeScroll 0 0", it is still possible to move or resize windows
              across  the  edge  of  the  current  screen.  By  making  the  first  parameter  to
              EdgeResistance  10000  this  type of motion is impossible. With EdgeResistance less
              than 10000 but  greater  than  0  moving  over  pages  becomes  difficult  but  not
              impossible.

       EdgeScroll horizontal vertical
              Specifies  the  percentage  of  a page to scroll when the cursor hits the edge of a
              page. If you don't want any paging or scrolling when you hit the  edge  of  a  page
              include  "EdgeScroll  0  0"  in  your  .fvwmrc  file.  If you want whole pages, use
              "EdgeScroll 100 100". Both horizontal and vertical should be positive numbers.

              If the horizontal and vertical percentages are multiplied by  1000  then  scrolling
              will  wrap around at the edge of the desktop. If "EdgeScroll 100000 100000" is used
              fvwm will scroll by whole pages, wrapping around at the edge of the desktop.

       Font fontname
              Makes fvwm use font fontname instead of "fixed" for menus, the  resize  indicators,
              and icon labels (if IconFont is not specified).

       Function FunctionName
              Starts  the  definition  of  a  complex  function,  composed  of  the fvwm built-in
              functions, which will later be bound to a mouse button or key. FunctionName must be
              enclosed  in quotes.  Function entries are included on lines following the Function
              keyword. The definition ends with the key word EndFunction.  Function  entries  are
              specified  as  shown  in  the following example. The first word on each line is the
              built-in function which will be performed, followed the type of event which  should
              trigger  the  action  (enclosed  in  quotes),  followed by any additional arguments
              needed by the built-in function. Menus can be specified by using the Popup built-in
              as long as the menu was defined earlier in the configuration file.

              The  trigger  actions  which  are  recognized  are  Immediate,  Motion,  Click, and
              DoubleClick. Immediate actions are executed as soon as the function  is  activated,
              even  if  a window has not been selected. If there are actions other than immediate
              ones, fvwm will wait to see if the user is clicking, double-clicking,  or  dragging
              the  mouse.  After  the decision is made, fvwm will execute only the built-ins from
              the function definition whose trigger action matches the action  performed  by  the
              user.

              If  the  following example were bound to button 1 in a window title-bar, then, when
              button 1 is pressed, fvwm would wait 150 msec to see if the button is released.  If
              the  button  is  not  released  fvwm  will  start  a  move operation. When the move
              operation is complete a raise operation will be performed. If a button  release  is
              detected then fvwm will wait another 150 msec for a second click. If only one click
              is detected then the window will be raised. If two clicks are detected  the  window
              will  be  alternately raised and lowered. The 150 msec wait duration can be altered
              using the ClickTime option.
              Function "Move-or-Raise"
                  Move            "Motion"
                  Raise           "Motion"
                  Raise           "Click"
                  RaiseLower      "DoubleClick"
              EndFunction
              The clicking and double clicking concepts do not carry through  to  using  keyboard
              shortcuts.

              Two  special  functions  exist:  InitFunction and RestartFunction. The InitFunction
              will be called when fvwm is started for the first time in any X session and can  be
              used  to  start  modules,  set background patterns, and begin programs. The restart
              function will be called when fvwm is restarted. It can be used to start modules and
              set background patterns but probably should not be used to start programs.

       HiBackColor colorname
              Sets  the  background  color  of  the  selected  window  to colorname. When using a
              monochrome screen this option is ignored and white is used.

       HiForeColor colorname
              Sets the color of the selected window's title to colorname. When using a monochrome
              screen this option is ignored and black is used.

       Icon windowname bitmap-file
              Specifies  the bitmap to be used for a window when it is iconified.  The windowname
              can be an application's window name or class name and must be enclosed  in  quotes.
              The  bitmap-file  is  either  the full path name to a standard X11 bitmap file or a
              file in the  IconPath  or  PixmapPath.  The  specified  bitmap/pixmap  is  used  in
              preference to any icon supplied by the window itself.

              If  fvwm  is  compiled  with  XPM support for color icons then bitmap can be an XPM
              pixmap file.

              windowname should  be  enclosed  in  double  quotes  but  bitmap-file  should  not.
              Environment variables should not be used in the bitmap-file specification.

              If  windowname  is an empty string then the specified file is the default icon, and
              will be used if no other icon bitmap or pixmap can be found:
              Icon "" my-favorite-icon

              The Style command provides another (more general) method for specifying Icon.

       IconBox left top right bottom
              Defines regions of the screen in which to place icons. Up to four icon boxes can be
              defined.  If an IconBox line is provided then icons will automatically be placed in
              them, if possible. Each time a window is iconified a new place  is  found  for  it.
              Icon  boxes  are  searched for space going left to right, then top to bottom. Icons
              will not be auto-placed on top of other icons but they  may  be  placed  underneath
              application  windows.  If  left or right is negative, then fvwm will add the screen
              width to it. If top or bottom is negative, then fvwm will add the screen height  to
              it.  NOTE: -0 is not parsed as the right or bottom pixel on the screen. You have to
              use -1 instead.

              If no IconBox line is provided or all icon boxes are full,  then  fvwm  will  place
              icons near the current pointer location.

       IconFont fontname
              Makes  fvwm use font fontname for icon labels. If omitted, the menu font (specified
              by the Font configuration parameter) will be used instead.

       IconPath path
              Specifies a colon separated list of full path names  of  directories  where  bitmap
              (monochrome)  icons can be found. Each path should start with a slash. Note: if the
              M4 patches are included when fvwm is built, then m4 will want to  mangle  the  word
              "include"  which  will frequently show up in the IconPath or PixmapPath command. To
              fix this add undefine(`include') prior to the IconPath command.

       Key keyname Context Modifiers Function
              Binds a keyboard key to a specified fvwm built-in function.  Definition is the same
              as  for  a mouse binding except that the mouse button number is replaced with a key
              name. The keyname is one of the entries from /usr/include/X11/keysymdef.h, with the
              leading  XK_  omitted. The Context and Modifiers fields are defined as in the mouse
              binding.

              Binding a key to a title-bar button will not cause that button to appear  unless  a
              mouse binding also exists.

       Lenience
              The  ICCCM  states  that  if  an  application  sets the input field of the wm_hints
              structure to False, then it never wants the window manager to  give  it  the  input
              focus.  The only application that I know of which needs this is sxpm, and that is a
              silly bug with a trivial fix and has no overall effect on the program anyway. Rumor
              is that some older applications have problems too.

              If this parameter is set then fvwm will ignore this ICCCM convention.

       MenuBackColor colorname
              Sets  the menu background color. When using monochrome this option is ignored. This
              option is only available if fvwm is compiled with MENUCOLOR defined.

       MenuForeColor colorname
              Sets the menu foreground color. When using monochrome this option is ignored.  This
              option is only available if fvwm is compiled with MENUCOLOR defined.

       MenuStippleColor colorname
              Sets the color for shaded out entries in menus (for functions which are not allowed
              on the currently selected window). When using monochrome this option is ignored and
              a  stipple pattern is used.  This option is only available if fvwm is compiled with
              MENUCOLOR defined.

       Module ModuleName
              Specifies a module which should be spawned during initialization.  At  the  current
              time  the  available  modules  are  FvwmAudio,  FvwmBacker,  FvwmBanner, FvwmClean,
              FvwmDebug, FvwmIconBox, FvwmIdent, FvwmPager, FvwmSave,  FvwmSaveDesk,  FvwmScroll,
              FvwmWinList,  and  GoodStuff.  These  modules have their own man pages.  Module can
              also be used as a built-in. Modules can be short lived transient programs or,  like
              GoodStuff, can remain for the duration of the X session. Modules will be terminated
              by  the  window  manager  prior  to  restarts  and  quits,  if  possible.  See  the
              introductory section on modules.

       ModulePath
              Specifies  a  colon  separated  list of paths for fvwm to search when looking for a
              module to load.  Individual directories do not need trailing slashes.

       Mouse Button Context Modifiers Function
              Defines a mouse binding. Button is the mouse button number. If Button is zero  then
              any  button  will  perform  the  specified  function.   Context describes where the
              binding applies. Valid contexts are R for the root window,  W  for  an  application
              window,  T for a window title bar, S for a window side, top, or bottom bar, F for a
              window frame (the corners), I for an Icon window, or  0  through  9  for  title-bar
              buttons,  or  any  combination  of  these  letters. A is for any context except for
              title-bar buttons. For instance, a context of FST will  apply  when  the  mouse  is
              anywhere in a window's border except the title-bar buttons.

              Modifiers  is  any combination of N for no modifiers, C for control, S for shift, M
              for Meta, or A for any modifier.  For example, a modifier of  SM  will  apply  when
              both  the  Meta  and  shift  keys  are  down.  X11  modifiers mod1 through mod5 are
              represented as the digits 1 through 5.

              Function is one of fvwm's built-in functions.

              The title bar buttons are numbered with odd numbered buttons on the  left  side  of
              the title bar and even numbers on the right. Smaller-numbered buttons are displayed
              toward the outside of the window while larger-numbered buttons  appear  toward  the
              middle of the window (0 is short for 10). In summary, the buttons are numbered:
              1 3 5 7 9    0 8 6 4 2
              The  highest  odd  numbered  button  which has an action bound to it determines the
              number of buttons drawn on the left side of the title bar. The highest even  number
              determines  the  number or right side buttons which are drawn. Actions can be bound
              to either mouse buttons or keyboard keys.

       MWMBorders
              Substitutes MWM style 1 pixel wide relief lines instead of fvwm's 2 pixel borders.

       MWMButtons
              Disables button press feedback for all decorations except the title bar and  title-
              bar buttons, as in MWM.

       MWMDecorHints
              Causes  fvwm  to read the MOTIF_WM_HINTS atom from application windows and to parse
              and attempt to replicate the Motif behavior  with  regard  to  window  decorations.
              Note  that mwm allows function hints to affect window decorations but these effects
              are not replicated by this option.

       MWMFunctionHints
              Causes fvwm to read the MOTIF_WM_HINTS atom from application windows and  to  parse
              and  attempt  to  replicate  the  Motif  behavior  with  regard  to  allowed window
              functions.  Unlike mwm, which simply removes prohibited functions from the window's
              menus,  fvwm  simply  shades  out  the  prohibited  functions.  Also,  because fvwm
              implements some functions in user defined macros that  mwm  implements  internally,
              the mapping of prohibited functions is partially based on the menu item label.

       MWMHintOverride
              If  MWMFunctionHints  is used then maximization and iconfication are prohibited for
              transients. Also, windows can specify that the window manager should not destroy or
              delete  them.  Since  these MWM rules are kind of stupid, especially with regard to
              the transient windows, I provide this MWMHintOverride option. When it is used  menu
              items will be shaded out if MWM would prohibit their use, but the user can go ahead
              and select that item and it will operate as expected.

              The override should be used cautiously because some applications will break if  you
              override their mwm hints.

       MWMMenus
              Substitutes  MWM  look and feel menus in place of the standard fvwm versions.  This
              option also  triggers  a  few  other  mwm-style  options,  such  as  centering  the
              size/resize  window  on  the  screen,  instead of leaving it in the upper left, and
              switches the resize-on-initial-placement trigger action to  shift-button-1  instead
              of the twm style press-button-2

       NoBorder windowname
              Keeps  fvwm  from  putting  decorative  borders  on  windows named windowname. This
              command has no effect on the title-bar.  This  is  handy  for  clocks  and  similar
              gadgets that you don't want to take up too much space. windowname can be a window's
              name or its class.

              If you specify both NoBorder windowname and NoTitle windowname for the same  window
              in your .fvwmrc file the window will be completely undecorated.

              Windowname  can  contain  the wildcards "*" and "?" which match window names in the
              normal Unix filename matching manner. Actual "*", "?",  and  "\"  characters  in  a
              window name can be entered by preceding the character with a "\".

              The Style command provides another (more general) method for specifying NoBorder.

       NoBoundaryWidth Width
              Changes  the  width  of  the decorations for windows with no titles and no borders.
              The default is 1. Any positive or zero value is acceptable.  Decorations for  these
              undecorated  windows  have  the same context as the side-bars on normally decorated
              windows.

              The  Style  command  provides  another  (more  general)   method   for   specifying
              NoBoundaryWidth.

       NoPPosition
              Instructs fvwm to ignore the PPosition field when adding new windows.  Adherence to
              the PPosition field is required for some applications, but if you don't have one of
              those its a real headache.

       NoTitle windowname
              Keeps  fvwm  from  putting  a  title-bar  in  the  decorations  for  windows  named
              windowname. This is handy for clocks and similar gadgets that  you  don't  want  to
              take up too much space. windowname can be a window's name or its class.

              Windowname  can  contain  the wildcards "*" and "?" which match window names in the
              normal Unix filename matching manner. Actual "*", "?",  and  "\"  characters  in  a
              window name can be entered by preceding the character with a "\".

              The Style command provides another (more general) method for specifying NoTitle.

       OpaqueMove percentage
              Tells  fvwm  the  maximum  size  window with which opaque window movement should be
              used. The percentage is percent of the total screen area. With "OpaqueMove  0"  all
              windows  will  be moved using the traditional rubber-band outline. With "OpaqueMove
              100" all windows will be move as solid windows.  The  default  is  "OpaqueMove  5",
              which  allows  small  windows to be moved in an opaque manner but large windows are
              moved as rubber-bands.

       OpaqueResize
              Causes resize operations to be done with the window itself instead of an outline.

       Pager  X_Location Y_Location
              Enables a paging style of moving across the desktop. A Pager window (not a  pop-up)
              will  appear  at (X_Location, Y_Location). Miniature versions of all the non-sticky
              windows on the virtual desktop are shown in the pager.  The color of the  miniature
              version is the same as the color of the full-size window's border.

              In  the Pager window, pressing mouse button 1 will move the desktop viewport to the
              selected page (in click-to-focus mode; it will also move the keyboard focus to  the
              window  whose  miniature you click on).  Pressing button 2 on a window in the pager
              will begin a window move, using the miniature to quickly move the  window  anywhere
              on the desktop.  Pressing button 3 will move the top-left corner of the viewport to
              the location of the button press, even  if  it  does  not  line  up  with  a  page.
              Dragging  button  3  will  cause  the  selected  viewport to scroll as you move the
              pointer. The Pager is automatically sticky but does not automatically stay on top.

       PagerForeColor colorname
              Causes the pager foreground color to be colorname instead of black.   This  is  the
              color  used to highlight the current viewport in the pager window.  On a monochrome
              screen this option is ignored. If the NO_PAGER option is  set  when  building  fvwm
              this option is unavailable.

       PagerBackColor colorname
              Causes  the  pager  background  color  to  be  colorname  instead  of  white.  On a
              monochrome screen this option is ignored.  If  the  NO_PAGER  option  is  set  when
              building fvwm this option is unavailable.

       PagerFont fontname
              Makes  fvwm  use  font  fontname  for  writing  window  icon  names in the window's
              representation in the pager. If this option is omitted no names are written in  the
              pager windows.

       PagingDefault pagingdefaultvalue
              Tells  fvwm  if it should start up with paging enabled or disabled.  "PagingDefault
              0" will start fvwm with paging disabled; "PagingDefault 1"  will  start  fvwm  with
              paging enabled by default.

       PixmapPath path
              Specifies  a  colon  separated  list of full path names of directories where pixmap
              (color) icons can be found. Each path should start with a slash.

       Popup PopupName
              Starts the definition of a pop-up menu which will later be bound to a mouse  button
              or  key.  PopupName must be enclosed in quotes.  Menu entries are included on lines
              following the Popup keyword. The menu definition ends with the key  word  EndPopup.
              Menu  entries  are  specified as shown in the following example.  The first word on
              each line is the built-in function which will be performed, followed by the caption
              (enclosed  in  quotes)  which will be shown in the menu, followed by any additional
              arguments needed by the built-in function. Sub-menus can be specified by using  the
              Popup  built-in  as  long  as the sub-menu was defined earlier in the configuration
              file.
              Popup "Window Ops"
                  Title   "Window Ops"
                  Move    "Move"
                  Resize  "Resize"
                  Raise   "Raise"
                  Lower   "Lower"
                  Iconify "(De)Iconify"
                  Nop     " "
                  Destroy "Destroy"
                  Title   "HARDCOPY"
                  Exec    "Hardcopy"  exec xdpr &
                  Exec    "Hardcopy RV"  exec xdpr -rv &
              EndMenu
              Note that if a tab character is embedded in the caption of a menu  entry  then  the
              text  following  the  tab  will be entered into a second column in the menu and the
              entire menu will be left-adjusted. This is intended for shortcut labeling. The  tab
              character must really be a tab. If it is expanded into spaces it will not work! For
              example:
              Popup "Window Ops"
                  Title   "Window Ops  Alt-F1"
                  .
                  .
                  .
              Is the start of a left adjusted menu. Alt-F1 will be placed toward the  right  side
              of the menu.

              Shortcut  keys  may  be specified in the menu definition by preceding the character
              with an ampersand.  The ampersand will not be displayed but the character after  it
              will  be  displayed  underlined, and if the user presses the corresponding key then
              that item will be activated as if the user had clicked on it with the mouse.   Only
              alphabetic and numeric characters may be used as shortcut keys.  The shift state of
              the keyboard is ignored when testing shortcut characters. For example:
              Popup "Window Ops"
                  Maximize "Ma&ximise" 100 100
              EndMenu
              When this menu is popped up the 'x' will be underlined and  pressing  the  'x'  key
              will  cause  the  current  window  to be maximized. Shortcut keys are not operative
              unless MENU_HOTKEYS was defined when building fvwm.  If WINDOWLIST_HOTKEYS was also
              defined  then  hot  keys  are  automatically  added  to  the  WindowList when it is
              displayed.

       RandomPlacement
              Causes windows which would normally require  user  placement  to  be  automatically
              placed  in  ever-so-slightly random locations.  For the best of all possible worlds
              use both RandomPlacement and SmartPlacement.

       SaveUnders
              Causes the fvwm decoration frames to request save-unders.  This  can  significantly
              improve the performance during opaque moves but it causes a significant increase in
              memory usage.

       SloppyFocus
              This focusing mode is like focus-follows-mouse (the default) except that the  focus
              will  not  be removed from a window until your mouse enters a new window. Exiting a
              window to enter the root window will leave the focus unchanged.

       SmartPlacement
              Causes windows which would normally require  user  placement  to  be  automatically
              placed  in  a  smart  location  - a location in which they do not overlap any other
              windows on the screen. If no such position can be found user  placement  or  random
              placement  will be used as a fall-back method.  For the best of all possible worlds
              use both RandomPlacement and SmartPlacement.

       StartsOnDesk windowname desk-number
              This command causes windows whose name or  class  is  windowname  to  be  initially
              placed  on  desktop  number  desk-number.   windowname should be enclosed in double
              quotes. If the window requires interactive placement, an outline will be  displayed
              on the current desk but the window will appear on the specified desk.

              Windowname  can  contain  the wildcards "*" and "?" which match window names in the
              normal Unix filename matching manner. Actual "*", "?",  and  "\"  characters  in  a
              window name can be entered by preceding the character with a "\".

              The   Style   command   provides  another  (more  general)  method  for  specifying
              StartsOnDesk.

       StaysOnTop windowname
              These  windows always try to stay on top of the other windows. This might be  handy
              for  clocks or mailboxes that you would always like to be visible. If the window is
              explicitly lowered it will not try to force its way back to the  top  until  it  is
              explicitly raised. windowname can be a window's name or its class.

              Windowname  can  contain  the wildcards "*" and "?" which match window names in the
              normal Unix filename matching manner. Actual "*", "?",  and  "\"  characters  in  a
              window name can be entered by preceding the character with a "\".

              The Style command provides another (more general) method for specifying StaysOnTop.

       StdBackColor colorname
              Sets  the  background  color  for menus and non-selected windows to colorname. When
              using a monochrome screen this option is ignored and white is used.

              The  Style  command  provides  another  (more  general)   method   for   specifying
              StdBackColor.

       StdForeColor colorname
              Sets  the  foreground  color for menus and non-selected window titles to colorname.
              When using a monochrome screen this option is ignored and black is used.

              The  Style  command  provides  another  (more  general)   method   for   specifying
              StdForeColor.

       StickyBackColor colorname
              Sets  the background color for non-selected sticky windows to colorname. When using
              a monochrome screen this option is ignored and white is  used.  Only  available  if
              -DMORE_COLORS is used when compiling.

       StickyForeColor colorname
              Sets  the foreground color for non-selected sticky window titles to colorname. When
              using a monochrome screen this option is ignored and black is used. Only  available
              if -DMORE_COLORS is used when compiling.

       Sticky windowname
              Sticky  windows  "stick  to  the  screen's glass." That is, they don't move the the
              viewport into the virtual desktop changes.  windowname can be a  window's  name  or
              its class.

              Windowname  can  contain  the wildcards "*" and "?" which match window names in the
              normal Unix filename matching manner. Actual "*", "?",  and  "\"  characters  in  a
              window name can be entered by preceding the character with a "\".

              The Style command provides another (more general) method for specifying Sticky.

       StickyIcons
              Causes  icons  to  always stick to the screen's glass. That is, icons always follow
              you around the desktop. When a window is de-iconified it gets un-stuck. Some people
              find this a useful way of moving windows around.

       StubbornIcons
              Changes  de-iconification  behavior  a  bit.  Instead  of having windows always de-
              iconify themselves  on  the  current  page  they  de-iconify  into  their  original
              position.

       StubbornIconPlacement
              When  used  with  IconBoxes,  causes  icons  to avoid placing themselves underneath
              existing windows.

       StubbornPlacement
              When using SmartPlacement, causes new windows  to  avoid  placing  themselves  over
              icons.

       Style windowname options
              This  command  is intended to replace the commands NoBorder, NoTitle, StartsOnDesk,
              Sticky,   StaysOnTop,   Icon,   WindowListSkip,    CirculateSkip,    SuppressIcons,
              BoundaryWidth,  NoBoundaryWidth,  StdForeColor,  and  StdBackColor  with  a  single
              flexible and comprehensive command.  This command is used to set  attributes  of  a
              window  to  values  other  than  the  default  or to set the window manager default
              styles.

              windowname can be a window's name, class, or resource string. It  can  contain  the
              wildcards * and/or ?, which are matched in the usual Unix filename manner.

              options  is  a  comma  separated  list  containing  some  or  all  of  the keywords
              BorderWidth,     HandleWidth,NoIcon/Icon,     NoTitle/Title,     NoHandles/Handles,
              WindowListSkip/WindowListHit,    CirculateSkip/CirculateHit,   StaysOnTop/StaysPut,
              Sticky/Slippery,    StartIconic/StartNormal,    Color,    ForeColor,     BackColor,
              StartsOnDesk/StartsAnyWhere, IconTitle/NoIconTitle, and NoButton/Button.

              In  the  above  list some options are listed as style-option/opposite-style-option.
              The opposite-style-option for entries that have them  describes  the  fvwm  default
              behavior and can be used if you want to change the fvwm default behavior.

              Icon  takes  an  (optional)  unquoted  string  argument which is the icon bitmap or
              pixmap to use.

              StartsOnDesk takes a numeric argument which is the  desktop  number  on  which  the
              window should be initially placed.

              BorderWidth  takes a numeric argument which is the width of the border to place the
              window if it does not have resize-handles.

              HandleWidth takes a numeric argument which is the width of the border to place  the
              window if it does have resize-handles.

              Button  and  NoButton  take a numeric argument which is the number of the title-bar
              button which is to be included/omitted.

              Color takes two arguments. The first is the window-label text color and the  second
              is  the window decoration's  normal background color.  The two colors are separated
              with a slash. If the use of a slash causes problems then the separate ForeColor and
              BackColor options can be used.

              An example:
              # Change default fvwm behavior to no title-bars on windows!
              # Also define a default icon.
              Style "*" NoTitle,Icon unknown1.xpm, BorderWidth 4,HandleWidth 5

              # now, window specific changes:
              Style "Fvwm*"     NoHandles,Sticky,WindowListSkip,BorderWidth 0
              Style "Fvwm Pager"                 StaysOnTop, BorderWidth 0
              Style "*lock"     NoHandles,Sticky,StaysOnTop,WindowListSkip
              Style "xbiff"               Sticky,           WindowListSkip
              Style "GoodStuff" NoHandles,Sticky,WindowListSkip
              Style "sxpm"      NoHandles
              Style "makerkit"

              # Put title-bars back on xterms only!
              Style "xterm"     Title, Color black/grey

              Style "rxvt"      Icon term.xpm
              Style "xterm"     Icon rterm.xpm
              Style "xcalc"     Icon xcalc.xpm
              Style "xbiff"     Icon mail1.xpm
              Style "xmh"       Icon mail1.xpm, StartsOnDesk 2
              Style "xman"      Icon xman.xpm
              Style "matlab"    Icon math4.xpm, StartsOnDesk 3
              Style "xmag"      Icon magnifying_glass2.xpm
              Style "xgraph"    Icon graphs.xpm
              Style "GoodStuff" Icon toolbox.xpm

              Style "Maker"     StartsOnDesk 1
              Style "signal"    StartsOnDesk 3
              Note  that all properties for a window will be OR'ed together. In the above example
              "FvwmPager" gets the property StaysOnTop via an exact window name  match  but  also
              gets  NoHandles,  Sticky,  and  WindowListSkip  by  a match to "Fvwm*". It will get
              NoTitle by virtue of a match to "*". If conflicting  styles  are  specified  for  a
              window, then the last style specified will be used.

              If the NoIcon attribute is set then the specified window will simply disappear when
              it is iconified. The window can be recovered through the window-list.  If  Icon  is
              set  without  an  argument  then  the  NoIcon  attribute  is cleared but no icon is
              specified. An example which allows only the FvwmPager module icon to exist:
              Style "*" NoIcon
              Style "Fvwm Pager" Icon

       SuppressIcons
              Prevents icon windows from being created or drawn. When used with  the  window-list
              this provides a sort of icon manager.

              The   Style   command   provides  another  (more  general)  method  for  specifying
              SuppressIcons.

       WindowFont fontname
              Makes fvwm use font fontname instead of "fixed" for the window title bar.

       WindowListSkip windowname
              Causes windows with the indicated name to be left out of the window list.

              Windowname can contain the wildcards "*" and "?" which match window  names  in  the
              normal  Unix  filename  matching  manner.  Actual "*", "?", and "\" characters in a
              window name can be entered by preceding the character with a "\".

              The  Style  command  provides  another  (more  general)   method   for   specifying
              WindowListSkip.

       XORvalue number
              Changes  the  value with which bits are XOR'ed when doing rubber-band window moving
              or resizing. Setting this value is a trial-and-error process.

BUILT IN FUNCTIONS

       Fvwm supports a set of built-in functions which can be bound to keyboard or mouse buttons:

       Beep   Makes the computer beep.

       CirculateDown [ name window_name ]
              Causes the pointer to move to the next window in the  list  of  windows  for  which
              CirculateSkip has not not been specified.

              If the optional arguments are supplied then the focus will move to the first window
              whose name (or icon name or class) matches window_name.  The optional argument name
              is  required if window_name is supplied and is enclosed in quotes. This argument is
              the name which appears in menus if the function is called from a menu,  but  serves
              no purpose if the function is not called from a menu.

       CirculateUp [ name window_name ]
              Causes  the pointer to move to the previous window in the list of windows for which
              CirculateSkip has not not been specified.

              If the optional arguments are supplied then the focus will move to the first window
              whose name (or icon name or class) matches window_name.  The optional argument name
              is required if window_name is supplied and is enclosed in quotes. This argument  is
              the  name  which appears in menus if the function is called from a menu, but serves
              no purpose if the function is not called from a menu

              Here's an example that move the focus to an xterm window when Alt-F1 is pressed:
              Key F1 A M CirculateUp "whatever" xterm

       Close  If the window accepts the delete window protocol a message is sent  to  the  window
              asking it to gracefully remove itself. If the window does not understand the delete
              window protocol then the window is destroyed.

       CursorMove horizonal vertical
              Moves the mouse pointer by horizontal pages in the X direction and  vertical  pages
              in  the  Y  direction.  Either or both entries may be negative. Both horizontal and
              vertical values are expressed in percent of pages, so "CursorMove 100 100" means to
              move  down  and left by one full page. "CursorMove 50 25" means to move left half a
              page and down a quarter of a page. The CursorMove function  should  not  be  called
              from pop-up menus.

       Delete Sends  a  message  to a window asking that it remove itself, frequently causing the
              application to exit.

       Desk arg1 arg2
              Changes to another desktop (workspace, room).

              If arg1 is non zero then the next desktop number will be the current desktop number
              plus arg1. Desktop numbers can be negative.

              If arg1 is zero then the new desktop number will be arg2.

              The  number  of  active  desktops  is  determined  dynamically. Only desktops which
              contain windows or are currently being displayed are active. Desktop  numbers  must
              be between 2147483647 and -2147483648 (is that enough?).

       Destroy
              Destroys a window. Guaranteed to get rid of the window, but is a fairly violent way
              to terminate an application.

       Exec name command
              Executes command. command is not quoted but name is.  name is the name that appears
              in  a  menu, if that is where the function is called from. name is required even if
              the function is not called from a menu.

              The following example binds function key F1 in the root window, with no  modifiers,
              to  the  exec  function.  The  program  rxvt  will be started with an assortment of
              options.
              Key F1 R N Exec "rxvt" exec rxvt -fg yellow -bg blue -e /bin/tcsh &

       Focus  Moves the viewport or window as needed to make the selected window  visible.   Sets
              the  keyboard focus to the selected window.  Raises the window if needed to make it
              visible. Warps the pointer into the selected window  in  focus-follows-mouse  mode.
              Does  not  de-iconify.  This  function  is  primarily for use with a module such as
              FvwmWinList.

       Function
              Used to bind a previously defined function to a key or mouse button.

              The following example binds mouse button 1 to a  function  called  "Move-or-Raise",
              whose  definition  was  provided  as  an  example  earlier  in this man page. After
              performing this binding fvwm will execute to move-or-raise function whenever button
              1 is pressed in a window title-bar.
              Mouse 1 T A Function "Move-or-Raise"

       GotoPage  x y
              Moves  the  desktop viewport to page (x,y). The upper left page is (0,0), the upper
              right is (N,0), where N is one less than the current  number  of  horizontal  pages
              specified  in  the DeskTopSize command. The lower left page is (0,M), and the lower
              right page is (N,M), where M is the desktop's vertical size  as  specified  in  the
              DeskTopSize command. The GotoPage function should not be used in a pop-up menu.

       Iconify [ value ]
              Iconifies  a  window  if  it  is  not already iconified or de-iconifies it if it is
              already  iconified.  If  the  optional  argument  value  is   positive   the   only
              iconification  will  be  allowed.  It  the  optional  argument is negative only de-
              iconification will be allowed.

       Lower  Allows the user to lower a window.

       Maximize [  horizontal vertical ]
              Without its optional arguments Maximize causes the  window  to  alternately  switch
              from a full-screen size to its normal size.

              With  the  optional  arguments  horizontal  and  vertical,  which  are expressed as
              percentage of a full screen, the user can control the new size of  the  window.  If
              horizontal  is  greater  than 0 then the horizontal dimension of the window will be
              set to horizontal*screen_width/100. The vertical resizing is similar.  For example,
              the  following  will add a title-bar button to switch a window to the full vertical
              size of the screen:
              Mouse 0 4 A Maximize 0 100
              The following causes windows to be stretched to the full width:
              Mouse 0 4 A Maximize 100 0
              This makes a window that is half the screen size in each direction:
              Mouse 0 4 A Maximize 50 50
              Values larger than 100 can be used with caution.

              If the letter "p" is appended to each coordinate (horizontal and/or vertical), then
              the scroll amount will be measured in pixels.

       Module name ModuleName
              Specifies  a  module  which should be spawned. Modules can be short lived transient
              programs or can remain  for  the  duration  of  the  X  session.  Modules  will  be
              terminated by the window manager prior to restarts and quits, if possible.  name is
              a double-qouted string which has absolutely no significance, but must exist.

       Move [ x y ]
              Allows the user to move a window. If called from  somewhere  in  a  window  or  its
              border,  then  that  window  will be moved. If called from the root window then the
              user will be allowed to select the target window.

              If the optional arguments x and y are provided, then the window will  be  moved  so
              that its upper left corner is at  location (x,y). The units of x and y are percent-
              of-screen, unless a letter "p" is appended to each coordinate, in  which  case  the
              location is specified in pixels.

              Examples:
              Mouse 1 T A Move
              Mouse 2 T A Move 10 10
              Mouse 3 T A Move 10p 10p
              In  the  first example, an interactive move is indicated. In the second, the window
              whose title-bar is selected will be moved so that its upper left hand corner is  10
              percent  of  the  screen  width in from the left of the screen, and 10 percent down
              from the top. The final example moves the window to coordinate (10,10) pixels.

       Nop    Does nothing. This is used to insert a blank line or separator in a  menu.  If  the
              menu item specification is Nop " ", then a blank line is inserted. If it looks like
              Nop "", then a separator line is inserted.

       Popup  This built-in has two purposes: to bind a menu to a key or  mouse  button,  and  to
              bind a sub-menu into a menu.  The formats for the two purposes differ slightly.

              To bind a previously defined pop-up menu to a key or mouse button:

                The  following  example  binds  mouse  buttons 2 and 3 to a pop-up called "Window
                Ops", whose definition was provided as an example earlier in this man page.   The
                menu will pop up if the buttons 2 or 3 are pressed in the window frame, side-bar,
                or title-bar, with no modifiers (none of shift, control, or meta).
                Mouse 2 FST N Popup "Window Ops"
                Mouse 3 FST N Popup "Window Ops"
                Pop-ups can be bound to keys through the use of the key modifier. Pop-ups can  be
                operated  without  using  the  mouse  by binding to keys and operating via the up
                arrow, down arrow, and enter keys.

              To bind a previously defined pop-up menu to another menu, for use as a sub-menu:

                The following example defines a sub menu, "Quit-Verify" and binds it into a  main
                menu, called "Utilities":
                Popup "Quit-Verify"
                    Title   "Really Quit Fvwm?"
                    Quit    "Yes, Really Quit"
                    Restart "Restart Fvwm" fvwm
                    Nop     ""
                    Nop     "No, Don't Quit"
                EndPopup

                Popup "Utilities"
                    Title   "Utilities"
                    Exec    "Xterm"         exec xterm &
                    Exec    "Rxvt"          exec rxvt &
                    Exec    "Top"           exec rxvt -T Top -n Top -e top &
                    Exec    "Calculator"    exec xcalc &
                    Exec    "Xman"          exec xman &
                    Exec    "Xmag"          exec xmag &
                    Nop     ""
                    Popup   "Exit Fvwm"     Quit-Verify
                EndPopup
                Sub-menus  must  be defined prior to the main menu in which they are bound.  Sub-
                menu nesting can be arbitrarily deep.

       Quit   Exits fvwm, generally causing X to exit too.

       Raise  Allows the user to raise a window.

       RaiseLower
              Alternately raises and lowers a window.

       Refresh
              Causes all windows on the screen to redraw themselves.

       Resize [ x y ]
              Allows the user to resize a window.

              If the optional arguments x and y are provided, then the window will  be  moved  so
              that its upper left corner is at  location (x,y). The units of x and y are percent-
              of-screen, unless a letter "p" is appended to each coordinate, in  which  case  the
              location is specified in pixels.

       Restart  name WindowManagerName
              Causes  fvwm  to  restart itself if WindowManagerName is "fvwm", or to switch to an
              alternate window manager if WindowManagerName is other than "fvwm".  If the  window
              manager  is not in your default search path, then you should use the full path name
              for WindowManagerName.

              WindowManagerName  is not quoted but name is.  name is the name that appears  in  a
              menu,  if  that  is where the function is called from. name is required even if the
              function is not called from a menu.

              This command should not have a trailing ampersand or any command line arguments and
              should  not make use of any environmental variables. Of the following examples, the
              first three are sure losers, but the third is OK:
              Key F1 R N Restart " " fvwm &
              Key F1 R N Restart " " $(HOME)/bin/fvwm
              Key F1 R N Restart " " twm -f .mystartupfile
              Key F1 R N Restart " " /home/nation/bin/fvwm

       Stick  Makes a window sticky if it is not already sticky, or non-sticky if it  is  already
              sticky.

       Scroll horizonal vertical
              Scrolls  the  virtual desktop's viewport by horizontal pages in the x-direction and
              vertical pages in the y-direction. Either or both entries  may  be  negative.  Both
              horizontal  and  vertical  values are expressed in percent of pages, so "Scroll 100
              100" means to scroll down and left by one full page. "Scroll 50 25" means to scroll
              left  half  a  page and down a quarter of a page. The scroll function should not be
              called from pop-up menus. Normally, scrolling stops at the  edge of the desktop.

              If the horizontal and vertical percentages are multiplied by  1000  then  scrolling
              will  wrap around at the edge of the desktop. If "Scroll 100000 0" is executed over
              and over fvwm will move to the next desktop page on each execution  and  will  wrap
              around at the edge of the desktop, so that every page is hit in turn.

              If the letter "p" is appended to each coordinate (horizontal and/or vertical), then
              the scroll amount will be measured in pixels.

       Title  Does nothing. This is used to insert a title line in a popup or menu.

       TogglePage
              Temporarily disables edge scrolling. Edge scrolling can be  re-enabled  by  calling
              this again.

       Wait name
              This built-in is intended to be used in fvwm functions only. It causes execution of
              a function to pause until a new  window  name  name  appears.  Fvwm  remains  fully
              functional  during  a  wait. This is particularly useful in the InitFunction if you
              are trying to start windows on specific desktops:
              Function "InitFunction"
                   Exec "I"  exec xterm -geometry 80x64+0+0
                   Wait "I"  xterm
                   Desk "I"  0 2
                   Exec "I"  exec xmh -font fixed -geometry 507x750+0+0 &
                   Wait "I"  xmh
                   Desk      "I"  0 0
              EndFunction
              The above function starts an xterm on the current desk, waits for it to map itself,
              then  switches  to  desk  2 and starts an xmh. After the xmh window appears control
              moves to desk 0.

       Warp [ name window_name ]
              Same as CirculateDown but de-iconifies any iconified windows as it focuses on them.

       WindowsDesk new_desk
              Moves the selected window the the desktop specified as new_desk.

       WindowList arg1 arg2
              Generates a pop-up menu (and pops it up) in which the title and geometry of each of
              the  windows currently on the desk top are shown. The geometry of iconified windows
              is shown in brackets. Selecting an item from the window list pop-up menu will cause
              that  window  to  be moved onto the desktop if it is currently not on it, will move
              the desktop viewport to the page containing the  upper  left  hand  corner  of  the
              window, will de-iconify the window if it is iconified, and will raise the window.

              If  arg1  is  an  even number then the windows will be listed using the window name
              (the name that shows up in the title-bar). If it is odd then the window's icon name
              is used.

              If  arg1  is  less  than 2 then all windows on all desktops (except those listed in
              WindowListSkip directives) will be shown.

              If arg1 is 2 or 3 then only windows on the current desktop will be shown.

              If arg1 is 4 or 5 then only windows on desktop number arg2 will be shown.

KEYBOARD SHORTCUTS

       All (I think) window manager operations can be performed from the  keyboard  so  mouseless
       operation  should  be  possible.  In  addition  to scrolling around the virtual desktop by
       binding the Scroll built-in to appropriate keys, pop-ups, move,  resize,  and  most  other
       built-ins  can  be bound to keys. Once a built-in function is started the pointer is moved
       by using the up, down, left, and right arrows, and the action is  terminated  by  pressing
       return.   Holding down the shift key will cause the pointer movement to go in larger steps
       and holding down the control key will cause the cursor movement to go  in  smaller  steps.
       Standard emacs and vi cursor movement controls (^n, ^p, ^f, ^b, and ^j, ^k, ^h, ^l) can be
       used instead of the arrow keys.

SUPPLIED CONFIGURATION

       A sample configuration file, system.fvwmrc, is supplied with the fvwm distribution. It  is
       well commented and can be used as a source of examples for fvwm configuration.

USE ON MULTI-SCREEN DISPLAYS

       If  the  -s  command line argument is not given, fvwm will automatically start up on every
       screen on the specified display. After fvwm starts each screen is  treated  independently.
       Restarts of fvwm need to be performed separately on each screen. The use of EdgeScroll 0 0
       is strongly recommended for multi-screen displays.

       You may need to quit on each screen to quit from the X session completely.

       Multi-screen support is only available if fvwm is compiled with -DMULTIPLE_SCREENS

BUGS

       As of fvwm 0.99 there were exactly 39.342 unidentified bugs. Identified bugs  have  mostly
       been  fixed,  though.  Since  then  9.34 bugs have been fixed.  Assuming that there are at
       least 10 unidentified bugs for every identified one, that leaves us with 39.342 -  9.32  +
       10 * 9.34 = 123.402 unidentified bugs. If we follow this to its logical conclusion we will
       have an infinite number of unidentified bugs before  the  number  of  bugs  can  start  to
       diminish,  at  which point the program will be bug-free.  Since this is a computer program
       infinity = 3.4028e+38 if you don't insist on double-precision. At the current rate of  bug
       discovery  we should expect to achieve this point in 3.37e+27 years. I guess I better plan
       on passing this thing on to my children....

       Binding a key to a window decoration but not to the window itself is  discouraged  because
       when  the  key-press  event  finally gets to the window it will be marked as SYNTHETIC and
       will be ignored by many applications.

       Bug reports can be sent to fvwm@wonderland.org.
