Ok I've redid the code to make any key rebindable to non-alpha keys. I'll also add a note to the keyboard ini. One of these days I'll make a nice menu to rebind them. Expect an update tonight (can't upload at my 'real' job) :).
//Left Shift = 160
//Right Shift = 161
//Alt = 17
//Control = 18
//Space = 32
