I'm curious. Why on earth would you want to re-assign Command-Q? It's so very useful as an OS-level command to quit the running application (in OS X at least). Whether or not there's a way to do this, it's, in my opinion, a less than good idea.
It is because our short key is the first character of our forms. All of our forms can be assigned, except Quotation which will be command-Q. Well, if the command-Q cannot be reassigned, we will use option+command+X as out short key.
