My keyboard has a pair of keys the left and right of the up arrow key, but VO isn't picking them up at all -- it just doesn't register at all when I press the button (unlike my control key problem, where it registers but shows up as a box).

xev reports the following when I press the keys (left, then right):

It would make my gaming life much easier (and prolong my existence significantly) if I could bind those keys to commands in the game. Running Vendetta on Linux amd64, if it makes any difference.
