I’ll use it with some emulators to trigger the menu bar so I can adjust settings.

I used it in fallout 4 to zoom since the pop it text was so small.

I used it a bit for save states and fast forwarding at one point too.

Depends on the game. Most common setup is just mapping the ABXY buttons to them, so I don’t have to take my finger off the right thumb stick to press them. In Elden Ring I use them for dpad presses instead, because I need to cycle spells/use recovery items without stopping moving.

I know a lot of people use them for L3 R3 instead of clicking the sticks.

In a couple games with smaller text I use one for toggling the magnifier, or in keyboard heavy games for opening the keyboard.

One of the laziest way that I use on all my game is to bind them to joystick presses(really can’t hold joysticks down while twisting it all over).

Two on the left goes to left joystick, two on the right goes to the right joystick.(Yes I bind two at a time since I find pressing them individually is hard when panicking.)

For RTS (especially AoE II DE) I use them as:

• the SHIFT key(create 5 units instead of 1 when hold)
• activator for a different action group, where the joystick are mapped to a circular menu. E.g. one of these menu assigns units to one of the 6 quick groups in my circular menu, and I can then select these units with just the right joystick (no button pressed). Another one activates a right joystick circular menu to go to a building (and I did map nearly all building types…)

I can also combine these, to e.g. select all barracks

I actually bind the top two as clones of the bumpers, Maybe I just have small hands and that’s why I’ve always liked PlayStation controllers more? But the bumpers on the Deck feel like a reach and not somewhere to comfortably rest your fingers on.

For the other two it’s normally duck & jump, or some button you have to regularly hold down while doing other things.

The only time I ever use them is by accident.

Playing heaps of Kingdom Come: Deliverance at the moment, I have one set to toggle Up and B for autorun, and another to take a screenshot. I’m sure I’ll find more uses the longer I have it.

My favorite use of back buttons is in games where there’s long, pretty, treks of exploration. From Monster Hunter: World to Red Dead Redemption and more, I always set up a back binding to an auto-walk.

Press and hold to toggle, adjust the timing to something a little longer than normal, and revel in stoned pleasure at the sprawling landscapes while you pack another bowl without losing time towards your next destination. It’s awesome! If the game allows, you can set up sprinting this way too even for those pesky tap to run ones (looking at you RDR).

The press and hold to toggle is important because it allows me to keep the button bound to a roll, which is often nice for games like Monster Hunter where I can keep my fingers on important camera control and direction/attack inputs while keeping a getaway button available

Depending on the game, R1 and L1, and other times just the usual ABXY with some per game adjustments.

Honestly, I don’t. They don’t do anything and I only click them while bored on waiting screens.

For emulators:

• L4-R4 select save state slot, L5-R5 save/load
• Not back buttons, but: Select + A/B/X/Y for Ctrl-Q, F11, etc

In general:

• Press R4 to start pressing A every 500ms so e.g. it picks the next level and various confirmation popups automatically
• Press L4 once to keep another button pressed, e.g. R1 in racing games

I don’t remember any others off the top of my head, but the gist is that when I’m annoyed by some weird specific input I start fiddling with Steam input for a few minutes to try and make it work more easily 😅

bottom left is crouch, bottom right is jump. I use the same bindings with my modded dualsense.

Clones of face buttons.

Discord Push-to-Talk.

In Factorio the keyboard modifiers (alt, ctrl) are back there.

I’ve only used them in Prey

i use mine a lot. for WoW I have them set to scroll wheel in and out, auto run and mount

for other games I tend to use them for combo button presses. or set up specific layer commands with them.

I often at least map two of them to joystick buttons, which or for example used to lock targets in many 3D games.

Pressing the real joystick buttons usually hurt my thumbs so bad so I love this feature 👍
