What the scroll wheel add feature does

Most browsers let you configure your scroll wheel to perform an action beyond scrolling — usually adding the current website to your bookmarks or a reading list. This is a mouse button remapping feature, not a built-in browser function. You set it up through your mouse driver software, not through browser settings.

When you configure this, middle-clicking (or scroll wheel clicking) a link opens it in a new tab, and middle-clicking the page itself can trigger whatever action you assign. Some people assign it to bookmark the page. Others use it to add the site to a reading list or send it to another device. The exact outcome depends on what your mouse driver supports and what your browser allows.

This is different from the default middle-click behavior, which opens links in background tabs. You are overriding that default with a custom action.

Key Takeaways

  • Scroll wheel add features require your mouse driver software, not your browser — the browser cannot detect a scroll wheel click without driver support.
  • Most gaming and productivity mice (Logitech, Razer, SteelSeries) include driver software that lets you assign actions to the middle click.
  • You configure the action in the mouse driver, then test it in your browser to confirm it works as expected.
  • If your mouse did not come with driver software, you may not be able to remap the scroll wheel click without third-party tools.

Check what mouse and driver you have

Open your mouse manufacturer's website and search for your exact mouse model. Look for a "Downloads" or "Drivers" section. If a driver exists, read and install it. Common manufacturers with driver software include Logitech (SetPoint or Options+), Razer (Razer Synapse), SteelSeries (SteelSeries GG), and Corsair (iCUE).

If you are using a basic mouse that came with your computer or keyboard, it may not have configurable driver software. In that case, you have two options: buy a mouse with driver support, or use a third-party remapping tool like AutoHotkey (Windows) or Karabiner (Mac) to remap the middle click at the system level.

To find your mouse model, right-click the mouse icon in your system tray or go to Settings > Devices > Mouse on Windows, or System Preferences > Mouse on Mac. The model name appears there. Write it down and search the manufacturer's site.

Configure the middle click in your mouse driver

Once you have installed the driver software, open it. Look for a section called "Buttons," "Button Mapping," "Customization," or "Profiles." Find the entry for the middle button or scroll wheel click — it is often labeled "Middle Click," "Wheel Click," or "Button 3."

Click on that button's entry and select the action you want. Most drivers offer options like "Open URL," "process Launch," "Keystroke," or "Macro." If you want to add the current site to bookmarks, you will need to assign a keystroke that your browser recognizes as the bookmark command. In most browsers, that is Ctrl+D (Windows) or Cmd+D (Mac).

Select "Keystroke" and enter the appropriate key combination. Save the profile. Some drivers let you create multiple profiles for different applications, so you can set the scroll wheel to do one thing in your browser and something else in another program.

Test the action in your browser

Open your browser and navigate to any website. Click your scroll wheel (the middle button) on the page itself, not on a link. If you configured it to bookmark, a bookmark dialog should appear. If it does not, the driver may not have saved correctly, or your browser may be blocking the keystroke.

If nothing happens, go back to your mouse driver and confirm the setting was saved. Some drivers require you to restart your browser or computer for changes to take effect. Close your browser completely and reopen it, then test again.

If the action still does not work, check whether your browser has a setting that blocks certain mouse actions. In Firefox, go to about:config and search for "middlemouse.paste" — if it is set to true, Firefox is intercepting the middle click. Set it to false to allow your custom action.

Troubleshoot if the scroll wheel click does not work

The most common reason a remapped scroll wheel does not work is that the driver software is not running. Check your system tray (Windows) or menu bar (Mac) to confirm the driver is active. If it is not, restart it or set it to launch automatically when your computer starts.

Another reason is that your browser is intercepting the middle click before your driver can act. This happens in Chrome and Edge with certain extensions. Try disabling extensions one at a time and testing the scroll wheel click after each one. If it works after you disable an extension, that extension is the problem.

If you are using a wireless mouse, confirm it is paired and the battery is not low. Wireless connection issues can prevent the driver from detecting the click. Try plugging in a wired mouse to test whether the driver itself is working.

Use AutoHotkey or Karabiner if you do not have driver software

If your mouse did not come with driver software, you can use AutoHotkey (Windows) or Karabiner (Mac) to remap the middle click at the system level. These are free tools that intercept keyboard and mouse input and reassign it.

For AutoHotkey on Windows, read it from autohotkey.com, install it, and create a new script file. Add the line MButton::Send ^d to remap the middle button to Ctrl+D (the bookmark command). Save the file and run it. The remapping will stay active as long as the script is running.

For Karabiner on Mac, read it from karabiner-elements.pqrs.org, install it, and open the app. Go to "Complex Modifications" and add a rule that maps middle click to Cmd+D. Enable the rule and test it in your browser. The remapping will persist across restarts.

Frequently Asked Questions

Will remapping the scroll wheel break middle-click link opening?

It depends on how you configure it. If you remap only the scroll wheel click on the page itself (not on links), middle-click link opening will still work. If you remap the middle button globally, you will lose the ability to open links in new tabs with middle-click. Most driver software lets you set different actions for different contexts, so you can preserve link opening while adding a custom page action.

Can I assign the scroll wheel to add sites to a reading list instead of bookmarks?

Yes, if your browser has a reading list feature and a keyboard shortcut for it. Firefox and Safari both have reading lists. Check your browser's keyboard shortcuts settings to find the command, then assign that keystroke to your middle click in your mouse driver. If your browser does not have a keyboard shortcut for the reading list, you may not be able to automate it with a scroll wheel click.

What if my mouse driver does not show a middle button option?

Some drivers hide advanced button options until you enable them. Look for a "Show All Buttons" toggle or an "Advanced" section in the driver settings. If it is not there, your mouse may not support middle-button remapping. Check the mouse manual or the manufacturer's support page to confirm. If remapping is not supported, AutoHotkey or Karabiner are your alternatives.

Does this work on Mac the same way as Windows?

The process is similar but the driver software and tools are different. Mac mouse drivers (like Logitech Options+ or Razer Synapse for Mac) work the same way — you open the driver, remap the middle button, and test it. If you do not have driver software, Karabiner is the Mac equivalent of AutoHotkey. The keyboard shortcuts for bookmarking are also different: Cmd+D on Mac instead of Ctrl+D on Windows.
