MagSpeed adaptive scroll-wheel
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.
