Both look OK to me.  And adding such doc is a definite
improvement.

It's not very clear to me from this doc what the relation
is between a key binding and a "binding for the character".
Keys and characters are different animals.  Clearly there
is a relation between them here, but it doesn't seem to
be made explicit.

But again, unless you want to try to clarify that, the
proposed doc is OK, and adding it improves things.
