Hmm.  Sounds a bit like the typical event handling in a GUI.  That
could be good.  So, off the top of my head, let's say each object had
a dictionary used to register keychord/event handler pairs, and that
the event handler functions were bound to the object as methods.  That
would allow the functions access to attributes and other methods of
the object.  If the function/method were bound to the object
containing most of the state needed by the method, there would be no
need to pass parameters to the method.  Other objects could be
accessed by navigating the object graph.

Did I understand you correctly?
