Just use the Hardware buttons with the "gas" touchscreen option...the arrow keys allow you to brake,gas, and turn. And the enter key is the nitrous... And another tip for the Asphalt 5 players: I discovered that if you choose the "touchscreen" option in the controllers menu, it also enables the "d-pad" or arrow keys to drive and "d"key is for nitrous and "x" key for break... Just a tip to everyone that prefers keyboard insted of touchscreen (like me)
