just saw a post that reminded me that a while back I used a micro controller and a knob to build myself a USB undo/redo gadget for code and photoshop. Can also be used to lower/rise computer volume.
@djlink@mluts Plenty of mechanical keyboards provide encoders for exactly this purpose. I use it on Sofle with an encoder on each side, one for vertical scrolling, the other for undo/redo https://josefadamcik.github.io/SofleKeyboard/
