    I've tried two ways of hiding menu commands when I switch between layouts
    in a CLIM application:

    (1)  enable-command/disable-command changes the font on the menu command
    name, and sensitizes/de-sensitizes the string;  however, I have one command
    that gets enabled, but whose font remains italicized (disabled).

    I would prefer to remove disabled commands from the command menu.  The
    difference in font style between enabled and disabled commands is not
    meaningful for users.

CLIM uses a different text style because graying over looks bad on lots
of display devices.

    (2)  and so I tried using a hierarchy of command tables.  However, I have
    not found a way to switch between command tables in my application.
    The display-command-menu function will display the command table that
    is defined in the :command-table parameter of the define-application-frame
    macro.  But I cannot seem to define my own display function that uses
    a different command table depending on application state.

    Are separate command tables intended to be used in this way?

Yes.

    How does one switch between command tables in CLIM?

(SETF (FRAME-COMMAND-TABLE <frame>) <command-table>)

You may wanto to call REDISPLAY-FRAME-PANE on your command menu pane to
force it to be redisplayed after you have switched command tables.
