Our new Logitech SmartWheel on your mouse

The Signature M650 and M650L feature SmartWheel scrolling that delivers precision or speed the moment you need it. Seamlessly switch between these two scrolling styles with the flick of your finger. Line-by-line (ratchet) scroll — get line-by-line precision when you need to focus on the details. Scroll slowly, you will feel each step on the wheel. Ideal for reading or precise navigation of items and lists. Speed (inertia) scroll — scroll faster for less- friction spinning. It will let you scroll faster and with less effort through long documents and web pages.

Horizontal Scroll

You can scroll horizontally with your mouse. This is done with a two-button combination: press and hold one of the side buttons and scroll with the wheel simultaneously. NOTE: The horizontal scroll is ON by default. You can customize this feature on the Point & Scroll tab in Logitech software. For more detailed information on Horizontal Scroll, click here.

Back/Forward buttons

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.

Logitech software lets you assign other useful functions to the buttons, including undo/redo, OS navigation, volume up/down, and more.

App-Specific Settings
Your mouse buttons can be assigned to perform different functions for different applications. You can assign the side buttons to control volume in Spotify, copy/paste in Microsoft Excel, or undo/redo in Adobe Photoshop.

When you install Logitech software, you can install predefined app-specific settings that will adapt the mouse button behavior to the selected applications.

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

	1	2
Default settings	Middle button	Forward	Back
Browser (Chrome, Edge, Safari)	Open link in a new tab	Forward	Back
Zoom/Teams	Middle button	Start/Stop Video	Mute/unmute Microphone
Media (Spotify, VLC, Quicktime)	Middle button	Forward	Back
Microsoft Excel	Pan (hold and move the mouse)	Redo	Undo
Microsoft Word	Autoscroll	Redo	Undo
Microsoft PowerPoint	Pan (hold and move the mouse)	Redo	Undo
Adobe Photoshop	Pan (hold and move the mouse)	Redo	Undo

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

Assign gestures to the side buttons

If you want more advanced functionality, you can assign any of the side buttons of the mouse to be the Gesture Button. This will transform your forward or back button into a powerful multi-function button allowing you to use gestures for desktop navigation, app management, pan, zoom, and more.

On the Mouse tab, select any side button (forward or back) button and click on Gesture Button.

By default, the gesture buttons will allow you to navigate between windows and desktops. In order to perform the gestures, you will need to hold the button while you move the mouse.

Check battery status

The LED on the top of the mouse indicates battery status. You can install Logitech software to receive battery status notifications, including low-charge warnings.

Battery life and replacement

Battery information:

• Requires 1 AA alkaline battery
• Expected battery life is up to 24 months

Installing a new battery

Left-handed version:

Logitech M650L has a left-handed version (M650L Left). It has the same feature definition as the right-handed version with the only difference being that the side buttons are on the right side of the mouse for better accessibility with your left thumb. Your mouse will still have the main click function on the left. If you prefer to swap it to the right button, you can use Logitech software.
