Key combinations, as used with the `Bind' command, are just strings containing the key label, optionally prefixed by a modifier key. For example,
"f1" % the [F1] key "ctrl-a" % [Ctrl-A] "c-a" % ditto |
Other modifiers are "Alt-" resp. "A-" and "Shift-" resp. "S-". Note that alphabetic keys are case insensitive in PCC 1.x, so it's neither useful nor allowed to bind things like "shift-a".
In PCC 1.x, not all possible combinations are allowed, because the DOS keyboard driver does not recognize all combinations. The following table lists all possibilities. If in doubt, try it; as a general rule, almost anything goes with "Alt-" and "Ctrl-". PCC2 has no such limits.
| "f1" .. "f12" | alone, or with Ctrl/Shift/Alt; |
| "home", "end" | alone, or with Ctrl/Alt; |
| "ins", "del" | alone, or with Ctrl/Alt; |
| "pgup", "pgdn" | alone, or with Ctrl/Alt; |
| "up", "down", "left", "right" | alone, or with Ctrl/Alt; |
| "tab" | alone, or with Ctrl/Shift/Alt; |
| the numbers "0" to "9" | alone, or with Alt or Ctrl+Alt; |
| the letters "a" to "z" | alone, or with Ctrl/Alt; |
| the characters "',-.,;=[\]`" | alone, or with Alt. Note that when used with Alt, these refer to the English keyboard layout; |
| "bs"/"backspace" | alone, or with Ctrl/Alt; |
| "esc" | alone, or with Alt; |
| "ret"/"enter" | alone, or with Ctrl/Alt; |
| "spc"/"space", "num5" | alone, or with Ctrl; |
| "numret"/"lfd" | with Alt (the [Enter] key on the numeric keypad); |
| "num*", "num+", "num-", "num/" | with Ctrl/Alt (operators on the numeric keypad); |
| "wheelup", "wheeldn" | alone (mouse wheel movement). |
All other single-character keystrokes can also be bound, and will not be further mangled by PCC (e.g., you can bind "@": English users will then use [Shift-2] to access that command, while German users have to use [AltGr-Q]).
In addition, there are the specialties "ctrl-2", "ctrl-alt--", "ctrl-spc" resp. "ctrl-space", "num5", "ctrl-num5", and "ctrl-print".
Note that "ctrl-g" can not be defined; it is the `refresh screen' command at all times. Programmers, beware: "ctrl-i" is not the same as "tab" (likewise for "ctrl-h" and "ctrl-m").
