A system for configuring keyboards using both frequency and alphabetical bases, as well as the resulting keyboards. The Keyboard Configuration System uses alphabetized and frequency-based sets of keys. The relevant alphabet is analyzed for letter use on a frequency basis. For maximum-fingers configurations, the frequency-ranked list is broken into rows. Letters are alphabetized horizontally within each row. For minimum-fingers configurations (Personal Digital Assistant keyboards), the frequency-ranked list is broken into columns. Letters are alphabetized vertically within each column. For dominant-fingers configurations, the frequency-ranked list is first broken into rows across six columns. These letters are alphabetized horizontally within each row. The remainder of the frequency-ranked list is then broken into columns. These letters are alphabetized vertically within each column. The resulting keyboards are then evaluated for alphabetical succession relative to the alphabetical direction. The system set forth herein may be adaptable to any written language.
