Abstract
A keyboard layout for a one-handed keypad having fifteen alphabetic keys. Each key has a primary letter and a secondary letter. The primary letter is keyed by solely striking the key, while the secondary letter requires striking a secondary key first or simultaneously with the primary alphanumeric key. The layout placement minimizes finger travel and keystrokes to generate the most common letters and digraphs in any language.
