ABSTRACT:
In a computer to which an external ten-key pad is connectable, whether or not the external ten-key pad is connected to the computer is detected. When the external ten-key pad is not connected, the overlay keys in the keyboard body function as letter keys or numeric keys depending on whether the computer is set in an NL state. When the external ten-key pad is connected, the overlay keys function as letter keys only.
