A method of creating a chording keyboard mapping table is described. An exercise is created that is performed by users of a keyboard for which a mapping table is desired. The psychomotor performance of the users' transitions between chords is recorded—as distinct from performance relating to chords. A first trial keyboard mapping table (from chords to symbols) is created, and the effectiveness of that table is measured by applying it to a text corpus and measuring the total psychomotor cost to enter that corpus with that table. The table is then permuted, and the cost recomputed. Trial tables are repeatedly permuted, with one or more preferred tables being used as the basis for the next iteration of permutations. This continues until a terminating event, such as minimal improvement, is reached. Variations as embodiments are described. Software to implement the method is claimed.
