MagSpeed Adaptive Scroll Wheel

The MagSpeed adaptive scroll wheel automatically shifts between two scrolling modes based on your scrolling speed:

Hyper-fast (free-spin) mode: Provides near-frictionless spinning, allowing you to quickly scroll through long documents and web pages.

Manual Mode Switching

You can manually switch between scrolling modes by pressing the mode shift button, which is assigned to the button on top of the mouse by default. Logitech Options Software allows you to disable SmartShift if you prefer a single scrolling mode and manual shifting. You can also adjust SmartShift sensitivity.

Back/Forward Buttons

Conveniently located, the back and forward buttons enhance navigation and simplify tasks. To move back and forward, press the back or forward button to navigate web or document pages, depending on the mouse pointer's location.

If you have a compatible Logitech Keyboard (e.g., MX Keys), the keyboard will also follow the mouse and switch computers simultaneously. This feature requires Logitech Options software installed on both computers.
