Don't just rely on default keyboard assignments to handle everything perfect if you're running XP SP2/SP3 or Vista. Some assignments have to be manually assigned first time or re-assigned from a default to a new keystroke or joystick button. For slew mode, this is especially the case. To move forward in slew, you'll find that some joysticks won't do the job anymore with these later, updated operating systems and the way that they interface with DirectX. I can use my stick twist rudder to rotate a bird left or right, but stick movement along the X and Y axis does nothing to move the bird. I had to re-assign lateral and forward/backward (X & Y) to the numpad keys to get this.
