map-keymap

map-keymap is a built-in function in `C source code'.

(map-keymap FUNCTION KEYMAP)

Call FUNCTION once for each event binding in KEYMAP.
FUNCTION is called with two arguments: the event that is bound, and
the definition it is bound to. The event may be a character range.

If KEYMAP has a parent, the parent's bindings are included as well.
This works recursively: if the parent has itself a parent, then the
grandparent's bindings are also included and so on.
