An encoding instrument held in substantially the palmar axis of a hand has a concavo-curved keypad surface accessibly equidistant to the thumb of the holding hand. The primary surface of the keypad is substantially not coincidental with a handle. Encoding switches mounted on the keypad are connected by cable or wireless signal transmission to operate selected functions. A movement control device mounted at the thumb end of the handle is operated by the thumb of the holding hand. Analog switch movement is positively and negatively manipulated by digit fingers of the holding hand.
