For Forward and Reverse Operation
Forward and reverse operation is controlled by the key, which is usually the smaller of the two handles and located on the right-hand side of the top of the controller. Typically the key is pushed forward for forward operation, and backwards for reverse operation. There is usually a neutral or "off" position between forward and reverse positions. The key can only be removed from the controller at the neutral position.

—Sydney Smith (1771–1845)
