That's interesting, I already asked myself the same question. Unfortunately the best
idea I had was to collect the information the event object offers and put them together to get the
event-sequence; for example I tried a little and it seems that event.type for KeyPress is 2, 
for KeyRelease 3; with event.keysym we could get the event-sequence:

def sequence(event):
    events = {'2':'KeyPress', '3':'KeyRelease'}
    return '<%s-%s>' %(events[event.type],event.keysym)

This could be very complicated if you want to catch any kind of event I'm afraid, especially if there's no documentation
about event types and everything needs to be tried first.
Maybe someone else has a better idea, if you find something please let me know, that's very interesting.

Thanks
