Subject: add statusbar message upon key-hander activation (#98)

Currently when running the key-handler the statusbar shows a
"Running key-handler..." message, but there's no indication of the prefix key
being pressed.

There's a slight functional benefit of this patch in the sense
that users can visually tell if the key-handler is listening on input or if the
key-handler has been aborted or not.
