When choosing the key sequences for Lisp programs to rebind, please
follow the Emacs conventions for use of various keys (@pxref{Key

This function returns the remapping for @var{command} (a symbol),

@cindex defining menus

A keymap acts as a menu if it has an @dfn{overall prompt string},
which is a string that appears as an element of the keymap.
of menus in advance. To force recalculation of the menu bar, call
@code{force-mode-line-update} (@pxref{Mode Line Format}).
- You've probably noticed that menu items show the equivalent keyboard key
-sequence (if any) to invoke the same command. To save time on
-recalculation, menu display caches this information in a sublist in the
-binding, like this:
-
-@c This line is not too long--rms.
-@example
-(@var{item-string} @r{[}@var{help}@r{]} (@var{key-binding-data}) . @var{real-binding})
-@end example
-
-@noindent
-Don't put these sublists in the menu item yourself; menu display
-calculates them automatically. Don't mention keyboard equivalents in
-the item strings themselves, since that is redundant.

@node Extended Menu Items
@subsubsection Extended Menu Items
@kindex menu-item
+@cindex extended menu item
An extended-format menu item is a more flexible and also cleaner
alternative to the simple format. You define an event type with a
@var{item-property-list}, has the form of a property list which contains
other information.
- When an equivalent keyboard key binding is cached, the extended menu
-item binding looks like this:
-
-@example
-(menu-item @var{item-name} @var{real-binding} (@var{key-binding-data})
- . @var{item-property-list})
-@end example
-
Here is a table of the properties that are supported:
@table @code
[work] '("Work" . work-command) 'break)
