Collectible Card Game Headquarters

I really like playing Forge on my Surface Pro. Is there a way to map the "Ok" "End turn" "Undo" "Cancel" options during a game to a keyboard key instead of having to click on it? Ideally I'd like to map the buttons on the surface pen to be able to do either of those commands.

I have included an image if I am being unclear.

Thank you for your time!
