* "Title" EXEC command_to_exec -params
* "Submenu" END
* "Workspaces" WORKSPACE_MENU
* "Title" built_in_command
* "Quit" EXIT
* "Quick Quit" EXIT QUICK
* "Menu Name" END
*
* Commands may be preceded by SHORTCUT key
*
* Built-in commands:
*
* INFO_PANEL - shows the Info Panel
* LEGAL_PANEL - shows the Legal info panel
* SHUTDOWN [QUICK] - closes the X server [without confirmation]
* REFRESH - forces the desktop to be repainted
* EXIT [QUICK] - exit the window manager [without confirmation]
* EXEC <program> - execute an external program
* SHEXEC <command> - execute a shell command
* WORKSPACE_MENU - places the workspace submenu
* ARRANGE_ICONS
* RESTART [<window manager>] - restarts the window manager
* SHOW_ALL - unhide all windows on workspace
* HIDE_OTHERS - hides all windows excep the focused one
* OPEN_MENU file - read menu data from file which must be a valid menu file.
* OPEN_MENU /some/dir [/some/other/dir ...] [WITH command -options]
* - read menu data from directory(ies) and
* eventually precede each with a command.
* OPEN_MENU | command
* - opens command and uses its stdout to construct and insert
* the resulting menu in current position. The output of
* command must be a valid menu description.
* The space between '|' and command is optional.
* SAVE_SESSION - saves the current state of the desktop, which include
* all running applications, all their hints (geometry,
* position on screen, workspace they live on, the dock
* or clip from where they were launched, and
* if minimized, shaded or hidden. Also saves the current
* workspace the user is on. All will be restored on every
* start of windowmaker until another SAVE_SESSION or
* CLEAR_SESSION is used. If SaveSessionOnExit = Yes; in
* WindowMaker domain file, then saving is automatically
* done on every windowmaker exit, overwriting any
* SAVE_SESSION or CLEAR_SESSION (see below). Also save
* dock state now.
* CLEAR_SESSION - clears any previous saved session. This will not have
* any effect if SaveSessionOnExit is True.
