I am trying to make it so that by hitting the windows key I launch an xterm, but I do not knwo the proper name or obscure number for the key. Thanks!
Try:
Key Super_L A N Exec exec xterm(Thomas, what did I say about the keysymdef.h? 
)
In a terminal: Run xev and focus the new window. Hit the key you want to know the symbol of and see the output in the terminal.
(Nice emoticon – the glasses suit you. 
)
I remember what you said about it, but you can’t rely on it as a single source of proper key-bindings.
