Is there a way to save/backup key binds?

[Double G]

I've been playing A16.4 for a couple days, just to see what it's like, and when I switch back to A21 all my key binds and game settings get defaulted. I have separate Steam folders for A21 and A16. I found the UserOptions file in the AppData folder but I don't see anything for key binds. Would there be a way for me not to have to keep redoing my settings when switching between the two alphas?

One easy way would be to make a second account on your PC and use it exclusively to play A16. I did not test it myself, but this should keep your settings separate.

I don't know if the 7d2d mod launcher also switches settings around when it switches between different alphas, but it promises to handle older versions of 7D2D, so it might.
