Product Overview

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.
In the Logi Options+ Software, you can decide to disable smart-shift if you prefer to stay in a single scrolling mode and always shift manually. You can also adjust the smart-shift sensitivity, which will change the speed required to automatically shift into free spinning.

Thumb wheel

Scroll side to side effortlessly with a stroke of your thumb.

Install Logi Options+ software to extend thumb wheel capabilities and more:

• Adjust thumbwheel scrolling speed, and direction
• Enable app-specific settings for the thumbwheel
  • Zoom in Microsoft Word and PowerPoint
  • Adjust brush size in Adobe Photoshop
  • Navigate your timeline in Adobe Premiere Pro
  • Switch between tabs in the browser
  • Adjust volume
  • Assign custom keystrokes to the wheel rotation (up and down)

Gesture Button
Install Logi Options + software to enable gestures.

To use the gesture button:

You can use gestures for desktop navigation, app management, pan and more. You can assign up to five different actions to the Gesture button. Or map gestures to other MX Master 3S buttons, including the middle button or manual shift button.

Back/Forward buttons
Conveniently located, the back and forward buttons enhance navigation and simplify tasks.

To move back and forward:

In addition to enabling the buttons for use with Macs, Logi Options+ software lets you map other useful functions to the buttons, including undo/redo, OS navigation, zoom, volume up/down, and more.

Darkfield 8000 DPI sensor
Install Logi Options+ software to enable the new capabilities of the Darkfield 8000 DPI Sensor

By default, the MX Master 3S Bluetooth Edition has a 1000 DPI configuration. In the Logi Options+ Software, you can extend the sensor range to up to 8000 DPI.

Enabling this option will allow you to work faster and more precisely, allowing you to adjust the pointer speed to match high resolution monitors.

App-Specific Settings
Your mouse buttons can be assigned to perform different functions for different applications. For instance, you can assign the thumb wheel to do horizontal scrolling in Microsoft Excel and zoom in Microsoft PowerPoint.

When installing Logi options+ , you will have the possibility to install predefined app-specific settings that will adapt the mouse button behavior to be optimized in selected applications.

Here are the app specific settings we have created for you:

With these settings, the Gesture button and the wheel mode-shift button are keeping the same functionality across all applications.

Each of these settings can be customized manually, for any application.

Flow
Work on multiple computers with a single MX Master 3S.

With Logi Flow, you can use the mouse cursor to move from one computer to the next. You can even copy and paste between computers, and if you have a compatible Logitech Keyboard, such as MX Mechanical, the keyboard will follow the mouse and switch computers at the same time.

You will need to install Logi Options+ software on both computers and follow these instructions.
