A method and apparatus for enhancing the operation of computer keyboards is disclosed. The invention allows touch-typing of nontouch-type keys by detecting a triggering sequence in the touch-type keys. For example, by holding down the Space Bar while depressing and releasing a second key and before release of the Space Bar, the Space Bar is seen to act as a Control key. Furthermore, the functions of nontouch-type keys may be superimposed upon touch-type keys and accessed in a similar manner. The invention interprets make codes which are generated by the keyboard when a key is depressed and a break code which is generated by the keyboard when a key is released. If a triggering sequence of codes is detected, then the normal function of one of the touch-type keys is altered. |
