mapping keys in joy2key?

[josh]

I can't, for the life of me, figure out how to map keyboard keys to buttons on my controller with joy2key. I just want to have the quick save and quick load keys on the L and R buttons so I don't have to lean up to my keyboard to use them (i know, lazy huh?). It works great otherwise, as a mouse. Can anyone tell me how to do this real quick?
