EdgeSlide PuttingPixelsTogether
Use this command to install EdgeSlide:
winget install --id=PuttingPixelsTogether.EdgeSlide -e EdgeSlide is a tiny Windows system-tray utility that turns the left and right edge strips of a Precision Touchpad into continuous sliders: slide the left edge to change screen brightness and the right edge to change master volume. It is single-finger only, so normal two-finger scrolling and other gestures pass through untouched, and it ignores edge touches while you are typing. It runs from the system tray with no main window.
