The ailerons are used to control roll rate. The flaps are used to increase lift at slow speeds. The elevators are use to control pitch. The rudder is used to control yaw. The spoilers are used to slow the aircraft quickly. The trim tabs are used to adjust back pressure to achieve straight and level flight with no control input.
I have only seen bolt type actions used.
