Hey Noah,

I recommend checking out Lundh's site (effbot) since he has lots of
information on Tkinter there. Here's his Tkinter event page:

http://effbot.org/tkinterbook/tkinter-events-and-bindings.htm

And there's this (less helpful):

http://docs.python.org/lib/node699.html

There's a whole chapter on events Grayson's Tkinter book, but I'm not
seeing constants defined. I think they might vary somewhat across
platforms anyway...but hopefully someone else more knowledgeable will
come along and address that.
