 *
 * 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.
 *                || will do the same, but will not cache the contents.
 * 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.
