I guess worth noting for Steam newbies:

The trackpads can be configured to act as basically any possible kind of input.

You can break them down into 4 way buttons, 8 way buttons, 2 buttons, one button... make them work as a joystick, or as a mouse... they click in a bit at multiple points...

So, if you prefer a different kind of thumbstick orientation, you can basically emulate it.

Literally all of the buttons on one of these things can be reconfigured to do a whole bunch of crazy shit, you can make macros, you can make it so that a little hud popup with scrollable selectable options pop up, you can make combos of key presses do different specific inputs, you can make a turbo function.... etc.

Hell, you can make the gyros act as a mouse/joystick input, in several different modes, maybe only when you hold the aim button down, if you want that.

Anything you run through Steam can be made to work this way with the Steam Input system they invented for with the Steam Deck, the Steam Controller 2.0 is basically a shrunk down Steam Deck without the PC and screen.

EDIT:

There is also an onscreen keyboard functionality, which pops up a keyboard overlay, and then you use both trackpads as basically two thumbs on a smart phone, sort of.

So, if you're playing a game that is 99% controller input, but has a few UIs popups where you get prompted to type in your name or something like that, or I guess even a chat box in an mmo, you can handle it with this.

Also also: Most/Many games come with preset default Steam Input layouts made by the developers. Also, Everyone who uses Steam is capable of basically uploading their control schema for any game to the cloud, and then you are capable of grabbing it and using it.

So, with some games, the developer provided inputs are good, sometimes users develop alternate schemes that are actually better/quite popular, or, maybe you could be the one to make a better config that people like!
