The Steam Controller's button icons are distinct in several ways from the general xbox buttons, As they have their unique and distinct from the general xbox icons. For example, you can see in the images below the button prompts show icons for unique features and properties of the steam controller, , like the gyro, touchpad's, buttons at the end of the triggers, and grips.

- Mafia III
- Team Fortress 2
- Warframe
- XCOM 2
- Portal 2
- Left for Dead 2
- The Witcher 3: Wild Hunt
- Wasteland 2
- Firewatch
- Cook, Serve, Delicious!
- CS:GO
- Defender's Quest: Valley of the Forgotten

If they are decided to be added, could to add them to the input settings guide too, as well ass add the new "Simultaneous controller KB/M" setting to the guide, as that's recently been added, but not to the guide yet, and is highly relevant to the Steam Controller :)
