MagSpeed adaptive scroll-wheel with SmartShift
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.
By default, mode shift is assigned to the button on top of the mouse.
In Logitech Options software, you can decide to disable SmartShift if you prefer to stay in one
scrolling mode and always shift manually. You can also adjust the SmartShift sensitivity, which
will change the speed required to automatically shift into free spinning.
