PLEASE tell me that's not by design. But even if it is, could you change this? :- )
Not sure...the KeyMapper maps all the keys that i could find in both APIs. I'll look into it to see why TAB is missing.
Actually, TAB isn't missing. At least not in the latest beta (http://jpct.de/download/beta/jpct.jar (http://jpct.de/download/beta/jpct.jar)). But you should be using this already, so i don't know why it should be missing. Maybe LWJGL doesn't report TAB as it should, but at least the mapping is in there...
Man, if it's lwjgl what should I do?
Try a pure LWJGL implementation and see if and how that works. Maybe the behaviour of TAB is somehow different to other keys...i don't know for sure, i've never used it.
