Hi, I'm using psychtoolbox and I want to deactivate every key except for the ones related to my program. I know I can writing something like this:
KeysIWantDisable = [4 7 8] % 4 5 7 represent keylog values
DisableKeysForKbCheck(KeysIWantDisable)
But I was wondering if there was a way to say "disable all the keys except..." because I won't really want to keylog the entire keyboard when I'm only using 4 keys.
Any ideas will be much appreciated, you guys have made this programming experience awesome so far, Brett

It's way too late but might be useful for somebody else. You can use :
DisableKeysForKbCheck(setdiff([1:256], [keysIWantEnabled]));

Why not just enumerate the keys you want to accept, and not proceed in execution until you get one of those?
You aren't disabling the keys, but you are still having largely the same effect.
This approach doesn't prevent the use of control-c or window shortcuts (function keys, alt-key combinations), either. But catching those can take extra levels of compilcation you may not want to deal with.

How about disabling the Microsoft/Desktop key?
