Configure the buttons

The Steam Deck has so many buttons. You should take advantage of them! Especially those rear paddle buttons, which aren’t always programmed in games because they aren’t typically found on a standard controller. That doesn’t mean you can’t use them.
Remapping the rear buttons can give you an advantage when playing certain games, like first-person shooters or competitive titles like Fortnite. They can also act as paddle shifters when you’re racing in Forza Horizon 5. To remap the trigger buttons, press the Steam button then move right twice to pull up the controller button map. Here, you can assign the rear buttons to any action.
