The keys operated by the Middle Fingers in the Second Nearest Row and the Fourth Nearest Row of the Alpha-Numeric Core, i.e. QWERTY D K 3 and 8, and the center key on the Number Pad are provided with hand positioning structures. Hand positioning with the Middle Fingers is based on the anatomical structure and bio-mechanical functioning of the arms, wrists, hands and fingers, and the hand positioning structures function by the neuro-sensory process of 2-point discrimination. With minimal practice, use of the hand positioning structures quickly functions at a subconscious reflex level. The hand positioning structures enable the operator to maintain visual focus and concentration on the text or display screen, and thereby eliminates unnecessary eye movement and text-reading errors due to eye movement. The structures and methods enable eliminating Home Row, and thereby eliminates awkward movements and contortions and eliminates the errors resulting from awkward movements and contortions. The structures and methods enable doing numbers with the hands positioned on the Number Row, rather than from Home Row, which also eliminates awkward movements and contortions, and improves speed, accuracy and efficiency in doing numbers. The hand positioning structures provide bio-mechanical balance and symmetry for the fingers and hands; improves keyboard operation by increasing operating speed, accuracy, efficiency, mobility, flexibility, fluidity of movement, and productivity; reduces operator mental, emotional, visual, and neuro-muscular stress and fatigue; and facilitates learning how to operate a keyboard. The cost of the structure is nominal; no employee retraining expense is required.
