After thinking about it: I implemented something like this myself.
Because resetting is tricky - and sometimes even something that you
don't want! - I just use a key binding that was unbound before.  So I
simply don't use any kind of resetting.  Hitting the key (again) when it
makes no sense may result in an error.  That's the case for other keys,
too, so...
