 event.type contains a numeric code (passed to the
 callback as a string).  the attached dictionary maps
 back from int(event.type) to the event name.

 however, it's probably better to use one binding per
 event type you need to handle, with distinct callbacks
 and/or lambdas:

     widget.bind("<Any-Button>", lambda e, cb=callback: cb(e, "button"))
     widget.bind("<Any-Key>", lambda e, cb=callback: cb(e, "key"))

     2: "KeyPress",
     3: "KeyRelease",
