ABSTRACT:
A compact keyboard has a plurality of pairs of individually movable side by side keys, each pair of which is on opposite sides of a vertical plane lying between such keys. All of the keys are operable by the fingers of one hand of a person and the keys of the compact keyboard correspond in number to the number of keys of a conventional QWERTY keyboard. The keys of the compact keyboard operable by the fingers of a person's left hand alternate with the keys operable by the person's right hand.
