elisp: Menu Keymaps

 
 21.17 Menu Keymaps
 ==================
 
 A keymap can operate as a menu as well as defining bindings for keyboard
 keys and mouse buttons.  Menus are usually actuated with the mouse, but
 they can function with the keyboard also.  If a menu keymap is active
 for the next input event, that activates the keyboard menu feature.
