ABSTRACT:
A symmetrical keyboard for computers, including computer terminals, word processors, typewriters, and similar equipment, and simulators of such equipment, wherein five rows of transverse keys are positioned and oriented in order to allow a user to move his or her left hand in a natural way that does not require unnatural "crabbing" (i.e. upward to the left and downward to the right) motions from the user's left hand. Further, the keyboard includes keys which are specifically positioned and configured so that equal numbers of letter keys are struck by each hand and opposing punctuation marks and symbols are struck by the opposing fingers of the user's left and right hands.
