Aw, that was just too obvious.
(A note to that effect in the Controls window would be user friendly.)
I did manage to bind wasd to the left joystick. How can I find what the mouse is bound to so that I can bind those functions to the controller also? I want to map mouse left/right, fwd/back to the controller's right joystick and eventually the clicks and scroll wheel to something else. All without losing the existing mouse bindings if that is possible. I don't see the mouse functions represented in the "Controls" tabs and perhaps they should be. Then people won't have to ask the question I just did.
I sure hope that someone who's a lot more game savvy than I am will soon create a full iomap.cfg file for the Xbox controller. Please, oh please.
BTW, this is of some importance to anyone, like myself, who want to use their Oculus Rift with the game and whose fingers are not trained for blind keyboard use. For us it would also be cool to be able to pull up a virtual keyboard for less used functions so we don't have to lift the Rift (hey, that should be an idiom) to get to them.
Thanks
