Abstract
Abstract The letter keys on the keyboards of typewriters and other typographical equipment are arranged in positions to accommodate either dextral or sinistral typists with greater speed and accuracy. By balancing the typing loads of hands and fingers, concentrating work on the home row, reducing the frequency of disabling and awkward typing patterns, and keeping either hand from typing too long by itself; most of the difficulty in typing English can be eliminated, and typing in other languages improved.
