  93  * Commands may be preceded by SHORTCUT key
  94  *
  95  * Built-in commands:
  96  *
  97  * INFO_PANEL - shows the Info Panel
  98  * LEGAL_PANEL - shows the Legal info panel
  99  * SHUTDOWN [QUICK] - closes the X server [without confirmation]
 100  * REFRESH - forces the desktop to be repainted
 101  * EXIT [QUICK] - exit the window manager [without confirmation]
 102  * EXEC <program> - execute an external program
 103  * SHEXEC <command> - execute a shell command
 104  * WORKSPACE_MENU - places the workspace submenu
 105  * ARRANGE_ICONS
 106  * RESTART [<window manager>] - restarts the window manager
 107  * SHOW_ALL - unhide all windows on workspace
 108  * HIDE_OTHERS - hides all windows excep the focused one
 109  * OPEN_MENU file - read menu data from file which must be a valid menu file.
 110  * OPEN_MENU /some/dir [/some/other/dir ...] [WITH command -options]
 111  *              - read menu data from directory(ies) and
 112  *                eventually precede each with a command.
 113  * OPEN_MENU | command
 114  *              - opens command and uses its stdout to construct and insert
 115  *                the resulting menu in current position. The output of
 116  *                command must be a valid menu description.
 117  *                The space between '|' and command is optional.
 118  *                || will do the same, but will not cache the contents.
 119  * SAVE_SESSION - saves the current state of the desktop, which include
 120  *                all running applications, all their hints (geometry,
 121  *                position on screen, workspace they live on, the dock
 122  *                or clip from where they were launched, and
 123  *                if minimized, shaded or hidden. Also saves the current
 124  *                workspace the user is on. All will be restored on every
 125  *                start of windowmaker until another SAVE_SESSION or
 126  *                CLEAR_SESSION is used. If SaveSessionOnExit = Yes; in
 127  *                WindowMaker domain file, then saving is automatically
 128  *                done on every windowmaker exit, overwriting any
 129  *                SAVE_SESSION or CLEAR_SESSION (see below). Also save
 130  *                dock state now.
 131  * CLEAR_SESSION - clears any previous saved session. This will not have
 132  *                any effect if SaveSessionOnExit is True.
