The game included a unique "active hand" system that allowed the player to manipulate the switches and controls without having to remember keyboard commands. Holding down the option key turned off mouse control of the aircraft, and made a hand-cursor appear that could operate the controls by clicking on them. The cursor changed as it moved over the controls to indicate what could be done, clicking, rotating or "rolling" the mechanical controls. Even complex weapons release modes could be controlled in this way, although doing so often required a series of clicks on different controls.
