how do change the num arrow keys and the wasd kets around? your current config means the one in focus needs to be moved with the mouse or wasd, but im an arrow man, can you switch them around for me please ?
or.... you could do a quick google search for AutoHotKey - find out what the key names for the arrow keys are and do a find-replace on WASD and be up and running

I'll even give ya a head start: AHK Keylist (extra hint, they're in the first section of the "Keyboard" section)
