121,122        79,7A          KEYDEF
     Pointer (LSB/MSB) to the keyboard definition table, initialized to
     64337 ($FB51), where the system keyboard table resides. You
     can redefine the keyboard by writing a 192-byte table and
     POKEing its address here. The table consists of three 64-byte
     portions: lowercase keys, SHIFTed keys, and CTRL keys. The sys-
     tem table has the following assignments:

     The next 64 bytes contain the shifted characters (for example, a
     shifted is A, 5 shifted is %; look at the upper characters on your
     keyboard). The following 64 are CTRL key characters (many
     graphics characters), You have to create a table for all 192
