convenient hint for users who do not know the key binding. If a
command has multiple bindings, Emacs normally displays the first one
it finds. You can specify one particular key binding by assigning an
-@code{:advertised-binding} symbol property to the command. For
-instance, the following tells Emacs to show @kbd{C-/} for the
-@code{undo} menu item:
-
-@smallexample
-(put 'undo :advertised-binding [?\C-/])
-@end smallexample
-
-@noindent
-If the @code{:advertised-binding} property specifies a key binding
-that the command does not actually have, it is ignored.
