A general-purpose manual input system for efficient symbol input comprises a keyboard (66) and software (68) running on a main unit (70) of a PC. The keyboard (66) comprises ten colored keys (74, 76, 78, 80, 82, 84, 86, 88, 90 and 92) and a highly-structured visual representation (94) of symbol-chord pairs. The keys of the keyboard (66) each have a different color and are operated by a different finger of a human operator. The visual representation (94) shows the assignment of chords to the symbols found on the standard computer keyboard. The visual representation (94) comprises several distinct group. Each group maps a distinct group of symbols to a distinct group of chords. Menu symbols and other selectable objects shown on the video display of the main unit (70) are dynamically labeled with single key and key sequence representations. A "hot" bar (169) shown on the video display of the main unit (70) is a flexible alternative to so-called hot keys found on many standard computer keyboards. |
