Steam Deck

In first-person games, I always rebind the jump to one of the back buttons. Coming from kbm, it weels weird that looking around and jumping at the same time is not possible.

I pretty much never use them, don't have the right hand shape and grip for it.

Some games have button layouts that make certain actions a pain. Two examples.

Horizon Zero Dawn - Healing is by default done by hitting dpad up. You generally want to press this button whenever you take damage to essentially trigger health regen, but doing so requires taking your thumb off the left stick, which means you can't simultaneously avoid even more damage. Bind to back button, problem solved.

BallisticNG - Weapons are bound to X, discard weapons is bound to B, and accelerate is on A. So when you pick up a weapon, to discard/use it you either have to drop thrust (bad, never do that) or awkwardly shimmy your thumb to either hit X or B without letting go of A. Bind X and B to back buttons, problems solved.

I use them in WoW for tricky keybinds. and in terraria they're pretty useful as well

I use the back buttons for all sorts of stuff. But the most common use is remapping ABXY to them. That way, I dont have to lift my thumb off the joysticks as much.

Also some games have easier menu navigation with a mouse, so I'll map left and right click to r1 and l1 and use a track pad to navigate menus.

I use them in place of the bumpers so my fingers can stay on the triggers.

Not much. On one hand, I don’t want to get too used to something that isn’t available anywhere else (controllers with back buttons are usually just able to be used as double for the face ones) and on the other hand… my main use is, as I found out, better to be avoided on the Deck. American Truck Simulator. Right now I don’t remember what I set them to, but I certainly have some cruise control options there. But the problem is that, if I’m tired at all, using the Deck if I end up doing a delivery at night, I fall asleep lmao. Learned that I am in fact not capable of shrugging off drowsiness while driving, glad I found out with a game…

In WR:SR (a Industrial City-Building Economy and Transport Simulator), there are different placing and overlay modes, like Snap-to-Grid (L4), Elevation (R4) and Underground view (R5), but I still need the first two buttons for zooming/radius(L1,R1), placing(R2)/removal(R2) confirm and the small buttons for placement elevation (for road/rails (and their bridges), pipes/cables) (X,B), mirroring (Y). (I forgot what A was for).

Basically every time you need more than two keys on the keyboard and the mouse simultanously, for the equivalent on the SD, the lower backbuttons come in handy.

I have a game that I was afraid of figuring out the controls yet; it is Cataclysm: Dark Days Ahead. In this game I will likely need every available button twice or something.

I've been playing a lot of Ziggurat 2 which is a roguelite fantasy-themed FPS with 4 categories of weapons. Instead of spamming Y to cycle through weapons, I can select my weapon directly with the back buttons.

In a visual novel, as another "advance text" button. In Crosscode, I have the "switch elements" arrow keys on the back buttons (you need to flip it on the fly a lot). In some games, I'll put the B-button action on R4 (particularly when it's a dodge-roll). If a game needs a random keyboard key out of the blue, I'll bind it on a paddle.

I'm playing through New Vegas right now. I have one of the back buttons assigned to quicksave. I also changed the default camera button to one of the back buttons, because I don't use it often enough to warrant it being on the bumpers. And I have just assigned one to toggle collision, because sometimes you need that when playing something built in the Gamebryo engine.

Nothing yet but this thread is giving me ideas :)

Going back.

So far the only games I've ever played on Deck that require them would be Portal 2 alongside the Portal 2 mod Revolution (or something along those lines). I think jump and maybe 1 other function is tied to the back buttons. Otherwise, I haven't messed around with controls enough to find a use for them.

I use the back buttons with Eurotruck simulator/ATS, and for whatever extra functions i want with other games. Also use them with Firefox on the desktop for paging forward or backward.

I use my deck for ffxiv a lot, so I bound dpad buttons to the back buttons. In any game, if you try to move and use something on the dpad at the same time, it's pretty rough. A claw grip is the typical way to handle this (Monster Hunter fans probably are familiar with this). This binding allows me to move and use dpad skills without hand cramping.

R5 is always dodge, B/circle, mostly so I don't have to claw grip. Rest depend on the game, but usually some mix of face buttons so I can keep thumbs on the sticks while picking up items or changing weapons/items/spells etc, and sometimes with a "hold to use" added in for the same reason.

I use the back buttons as alternative shoulder buttons.

My right bumper button broke and I can’t find cheap replacement daughterboards, so bandaid it is. I can’t just solder in a new switch because the leads on the PCB broke. Seems to be a failure common mode for the bumpers if you ever hit the corner or drop it. The way the bumper is designed transfers the full force directly to the PCB instead of to the shell or any actual structural component.

In games where I've have to hold a face button, yet use another I'll use the back buttons.

So I mirror ABXY in Hades II for example, and charge up my B spell while I dash away with A. Much more comfortable to charge with the back B and dash with the face A button.

flappy bappy wise the bottom ones are the joystick clicks, and the top ones are the shoulder buttons (i find my shoulder button pressed to be on the runliable side while using triggers)
