Im using rdfg aswell. before that I was using the arrow keys (doom time) and later I changed to esdf (duke time). but rdfg is making the most keys available for my left hand. Im also using a mouse with 5 buttons
oh and btw, I wont DL that demo just because I read your opinions.
I have given up on waiting for BIS to come back to their senses and do a real ArmA 2 successor.
