Defining A Key
A user can define the code that a key can produce. Each key has fj
four possible definitions: Normal, Alpha Shift, Shift and Control. The
Alpha Shift is toggled on/off by pressing the Commodore key. After
entering this mode, a small box will appear on the bottom of the | |
screen. The first key that is pressed is the key to be defined. The
current HEX (hexadecimal) value assigned to this key is displayed;
the user can then type the new HEX code for the key, or abort by fj
typing a non-HEX key. The following is a definition of the codes that
can be assigned to a key. (In ALT mode, codes are returned to the _
application; see ALT Mode below.) |i
