A line like
in your startup macro file will assign the command LongBreak to AlternateSpace, to find out which keycode to use please consult other literature. Beware: in some cases the Alternate key modifies the value of the returned keycode. To override the default bindings, set the command number to zero, this causes the character generated by the BIOS to be used for output.
Additionally some special keys can also be redefined:
| Key | Keycode |
| ShiftClrHome | -1 |
| ShiftUpArrow | -2 |
| ShiftDnArrow | -3 |
| ShiftLeftArrow | -4 |
| ShiftRightArrow | -5 |
| Insert | -6 |
| ShiftInsert | -7 |
| UnDo | -8 |
| ShiftUnDo | -9 |
| UnDo | -10 |
| Help | -11 |
| ShiftHelp | -12 |
| Help | -13 |
