Quick Start Guide

The speed-adaptive scroll wheel shifts between two scrolling modes automatically. As you scroll
faster, it will automatically shift from line-by-line scrolling to free-spinning.
Line-by-line (ratchet) mode — ideal for precise navigation of items and lists.
Hyper-fast (free-spin) mode — near-frictionless spinning, letting you fly through long
documents and web pages.
Switch modes manually
You can also manually switch between modes by pressing the mode shift button.
