What _do_ those keys do? I've been reading this thread and the only
fkeys of mine that do anything are f10-f12 which I've mapped to apple
scripts (or something, it's been a while) to control iTunes.

I use F5-F13 for actual parameter changes. I can't use F1-F4 because the system intercepts them and crashes my program.

My code (which admittedly I haven't touched in a while) prints out ^ [OP for F1, ^[OR for F3 and ^[OS for F4. F2 prints nothing. I'm sure there's some way to handle these but I never really cared that much to dig too deeply into it.



Looking at some code I wrote a few years ago, it looks like it sends
0x7f which should be del as defined by ascii.

7F did it! Thanks. Where on earth did you find this info? I checked
everywhere I could think of, including Google.

As Steve Checkoway rightly pointed out, 0x7f is ASCII DEL, which makes a
lot of sense for a delete key.


Now I think about it, I think delete keys returning 0x7f is pretty standard
terminal behaviour, and possibly the reason you couldn't find documentation
is that it's just assumed that you realise that this will happen?

I don't think it's really reasonable to assume that would happen. There is already a KEY_BACKSPACE. I just used getch and printed out the values returned.
