It'd be nice if users could opt in to have C-h v some-map RET show a
nice table of key bindings for that keymap.  I wrote a function that can

Alternatively, we can also add a key binding to help-mode so that users
can easily "switch" from describe-variable to describe-keymap, e.g. per
"K":

	C-h v message-mode-map RET K
