I hadn't been real chuffed about this because it gave me a reason to just leave Windows altogether, but I figured I should report it in case others are having the same issue. The key I've used for jump (alt menu - hamburger button) no longer works for game play. If I can't jump, kinda can't play the game. Bungie have something against lefties that use the arrow keys? Right arrow is also hard coded to bring up chat and will trigger in game on vehicles if boosting at the same time... but so is the enter key. Why are we hard coding the extra keys in the game and creating conflicts? Why is the alt-menu key no longer able to be used? I don't expect this to be resolved any time soon, so I'll go back to not playing the game at all since I can't really play it anyway. I'm not spending the time to relearn how to play right handed. Besides... I'm horrible using the mouse with my right hand and I'm even worse with controller (and I don't have a controller any more).
