Using the Speed-Adaptive Scroll Wheel
The main scroll wheel automatically switches between two modes:
- Mode clic a clic: Ideal for precise navigation of lists and individual items.

You can also manually switch between these modes by pressing the button located directly below the main scroll wheel.

The thumb wheel on the side of the mouse provides horizontal scrolling, which is particularly useful for navigating wide spreadsheets, timelines, or image galleries. By default, it scrolls horizontally, but its function can be customized via Logitech Options.
