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.

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. Use the Logitech Options
Software, to disable SmartShift if you prefer to stay in a single scrolling mode and shift
manually. You can also adjust the SmartShift sensitivity, which will change the speed required to
automatically shift into free spinning.
