The keys work fine using them about the keyboard (above qwerty), but the numpad square doesn't do anything there or elsewhere from what i've seen. Perhaps make it an option/toggle. I seem to recall that it worked in bg1/soa/tob, but could be mistaken.
I tried to look through the bug list to see if it was put anywhere else, but didn't see it. I also guess this is more of a feature then a bug? Ty for your time.
Edit: please move to not an issue thread if this is considered as such.
