cl-map-keymap is an alias for `map-keymap' in `cl.el'.

(cl-map-keymap FUNCTION KEYMAP)

This function is obsolete since 24.3;
use `map-keymap' instead.

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.
