Abstract
Abstract An improved key arrangement with the keys arranged to accommodate increased speed, and to facilitate learning by someone already familiar with the standard Qwerty key arrangement. The invention also includes a method of converting a conventional keyboard, used with a computer, to the keyboard of the instant invention, by converting codes emanating from the keyboard into codes representing those of the keyboard of the invention. Likewise typewriters may be converted by use of printing elements compatible with the new key arrangements.
