I literally just added that to the game, if you click tooltips. See this video.
Otherwise there is a list in the launcher before you start the game.

Still part of what i said earlier hasnt been fixed. The controls start of being fine but after playing a while it starts using w and s for up and down, shift and control for forward and backwards, the right stick start rotating me vertically sideways instead of horisontally and all of these keep changing according to which direction im looking in the game.
