How about mouse control?
At the moment the main control system is mouse driven. You basically move the cursor with the mouse and shoot. The ship moves with the cursor i.e. you move the cursor left the ship banks left (don't worry its not as complicated as it sounds and moves quite well). Its very easy to play like that and very responsive.
I will have a look at how Starlancer handles the keyboard routine and see if I can put something similar in.
