-This does not include bindings inherited from a parent keymap.
-FUNCTION receives two arguments each time it is called:
-the character (more generally, the event type) that is bound,
-and the binding it has.
-
-Note that passing the event type directly to `define-key' does not work
-in Emacs 19. We do not emulate that particular feature of Lucid Emacs.
-If your code does that, modify it to make a vector containing the event
-type that you get. That will work in both versions of Emacs."
