 The A&O Rotary Encoder Breakout Board with StemaQT running to a QT Pi and then that's off to USB. What I have it doing is sending USB HID key shortcuts which can be used to work with my editor. I can do some scrolling through as I try to find that exact point where I want to make an edit, let's say. I can press the center to play. I can left click multiple times to go fast reverse. I can go fast forward like so. If I find a spot that I want to place an edit, let's say I want to set the end point here, I'm just pressing up on my nav wheel and scroll over here and press down to get the out point. The A&O Rotary Encoder with I2C over StemaQT.
