Tab Wheel Scroll is a free Chrome add-on developed by jonathan.plantey. As the name suggests, it allows users to scroll through their open tabs with ease. This add-on provides two different methods for scrolling through tabs: using the ALT key with the mouse wheel or using the right mouse button with the mouse wheel.

To scroll through tabs using the ALT key, simply press and hold the ALT key on your keyboard and scroll the mouse wheel. Alternatively, you can right-click anywhere on the page and scroll the mouse wheel to navigate through your tabs.

It's important to note that when scrolling, your mouse should be positioned anywhere over the page content, but not over the tabs themselves. Additionally, if you disable and re-enable the extension, all tabs will need to be reloaded in order for the scrolling feature to work again.

Overall, Tab Wheel Scroll provides a convenient and efficient way to navigate through open tabs in the Chrome browser. Whether you prefer using the ALT key or the right mouse button, this add-on makes tab scrolling a breeze.
