Just had a thought...the OnePlus 6/6T have a physical switch used for silent/vibrate/ring in Android that is unused on mobile Linux. I want to use it to select between mouse, touchscreen, and onscreen keyboard modes. My TouchPad Emulator program allows using the touchscreen as a mouse but I use the volume keys to switch modes. Using this physical switch would be more convenient and now I want to test it. Anyone know if this switch is readable in postmarketOS?
