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.

You can use gestures for desktop navigation, app management, pan, zoom, and more. You can assign up to five different actions to the Gesture button. Or map gestures to other MX Master 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:
- Press the back or forward button to navigate web or document pages, depending on the location of the mouse pointer.
NOTE: On the Mac, enabling of the back/forward buttons requires installation of Logitech Options software. Install Logitech Options software to unlock new capabilities for the back/forward buttons. In addition to enabling the buttons for use with Macs, Logitech Options software lets you map other useful functions to the buttons, including undo/redo, OS navigation, zoom, volume up/down, and more.
App-Specific Settings Your mouse buttons can be assigned to perform different functions for different applications. For example, you can assign the thumb wheel to do horizontal scrolling in Microsoft Excel and zoom in Microsoft PowerPoint. With Logitech Options, you can install predefined app-specific settings that adapt the mouse button behavior to be optimized in selected applications. The following app-specific settings have been created for you: 
| 1 | 2 | 3 | |
| Default settings | Middle Button | Horizontal scroll | Back / Forward |
| Browser (Chrome, Edge, Safari) | Open link in a new tab | Switch between tabs | Back / Forward |
| Microsoft Excel | Pan (Hold and move the mouse) | Horizontal scroll | Undo / Redo |
| Microsoft Word | Pan (Hold and move the mouse) | Zoom | Undo / Redo |
| Microsoft PowerPoint | Pan (Hold and move the mouse) | Zoom | Undo / Redo |
| Adobe Photoshop | Pan (Hold and move the mouse) | Brush size | Undo / Redo |
| Adobe Premiere Pro | Pan (Hold and move the mouse) | Horizontal timeline navigation | Undo / Redo |
| Apple Final Cut Pro | Pan (Hold and move the mouse) | Horizontal timeline navigation | Undo / Redo |
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 With Logitech Flow, you can work on multiple computers with a single MX Master 3. You can use the mouse cursor to move from one computer to the next.

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

FAQS
This is definitely not a gaming mouse. The polling rate is only 125Hz, where a typical gaming mouse would poll 500-1000Hz, or more. Nothing is stopping you from playing games with it, but if you’re looking for something that will excel at gaming you’d be better served with a gaming oriented model.
Yes, but it involves knowing how to desolder the old switches and soldering in silent switches that you can find online somewhere or another silent mouse. I’ve silenced all my mice this way and it is actually really easy with the right tools.

I hope that the gesture button can be set to switch the mouse device. If multiple computers cannot be connected to the same domain, the function of data replication cannot be achieved. At least I hope that shortcut keys can be set to achieve the function of mouse switching between multiple systems.
The USB is plugged into the A system, and the B system uses Bluetooth, so you don’t need to turn to the back and press the button to switch
希望手勢按鍵可以設定切換 滑鼠裝置,如果無法將多台電腦都連在同一個網域下,不能達成資料複製的功能,至少希望可以設定快捷鍵,達成滑鼠在多系統切換的功能,
USB插在A系統,B系統使用藍芽,這樣不需要翻過去背面按按鈕就能切換
I see the thumbwheel can be assigned to “Brush Size” within PhotoShop. I use Affinity Photo, and was able to map all the other buttons/wheel the way I wanted, but “Brush Size” is not available for the thumbwheel.
Is there a way to add it? Thanks in advance!

How can I assign the thumbwheel to 'Brush Size' in Affinity Photo for the Logitech MX Master 3?
While the Logitech MX Master 3 includes a predefined "Brush Size" preset for Adobe Photoshop, it does not currently have a native preset for Affinity Photo. To achieve this functionality, you can manually map the thumbwheel using custom keystrokes in the Logitech Options (or Options+) software:
[to decrease and]to increase.]to Wheel forward/up and[to Wheel backward/down.Once configured, rotating the thumbwheel while in Affinity Photo will simulate these key presses to adjust your brush size.

Question: I just bought a Logitech MX MASTER 3.
Why is it that the S/N on the box S/N: 2203LZ50EYR9 is different from the S/N on the mouse S/N 2203LZ50DJB8 ?
Please clarify why there are two different S/N for the product I bought from your flagship shop 620 New Town Plaza Phase 1, Sha Tin Centre, NT. Hong Kong

Why is the serial number on the Logitech MX Master 3 box different from the serial number on the mouse itself?
It is normal for the serial number (S/N) on the packaging of Logitech products to differ from the serial number printed on the device itself. Logitech uses the serial number on the box to identify the complete retail package, while the serial number on the mouse identifies the specific hardware unit.
For warranty claims or product registration, you should generally use the serial number found on the device (the mouse). On the MX Master 3, this is typically located on the bottom of the mouse or can be viewed within the Logitech Options+ software when the device is connected.
If you need to verify the authenticity of your purchase from the Sha Tin Centre location, you can contact Logitech Support directly through their official website, though this S/N difference is standard manufacturing practice and not an indication of a problem.
