Is it possible with the mappings to map two keysets at once to one joystick port?
I find in some games I have to use both hands on the keyboard when jumping at 45% to get up/right up/left combinations which is too hard just using one hand and the arrow keys.
so use both hands but then want to be able to use arrow keys and shoot with the other hand if need be! :P

Or maybe a bi-direction key ..or on screen touch-control...or accelerometer...
