What do you use the back buttons for? - Lemmy

I have really been loving my steam deck lately. I’ve now played through Fallout 3, New Vegas, all of their respective DLCs, and am about 100hrs into 4 right now. Normally I play indie games since that’s where my interests are and I grow tired of the AAA jackassery. I mention that to illustrate that I do use and live the deck. But I guess I’m not creative enough to use the back buttons at all. So to the title question: * What games do you play that make the most use of the back buttons? * What functions are mapped to those buttons? * Or are you like me and just never use them?
