>How can I set a button "snap" turn 90 degrees with OVR advance settings
https://github.com/OpenVR-Advanced-Settings/OpenVR-AdvancedSettings#--rotation-page says you can set up a binding for it in steamvr bindings.

protip when steamvr is open you can open http://localhost:27062/dashboard/controllerbinding.html to do the bindings in desktop, a lot easier than clicking around in vr.
