Tab Pinner (Keyboard Shortcuts) is a free Chrome add-on developed by Brandon Buck. It aims to simplify the process of pinning and unpinning tabs by adding a convenient keyboard shortcut. Instead of right-clicking on a tab and selecting "Pin Tab," users can now use the default key binding of Ctrl + Shift + X (or Command + Shift + X on Mac OS X) to quickly pin or unpin tabs while browsing.

One of the key advantages of this extension is that it requires no special permissions and does not inject anything into web pages. Users can also customize the key binding to their preference by accessing the extensions page and selecting "Keyboard Shortcuts" from the sidebar menu. This allows for a more personalized and efficient browsing experience.

Overall, Tab Pinner (Keyboard Shortcuts) provides a simple and effective solution for pinning and unpinning tabs in Chrome. With its user-friendly interface and customizable key binding, users can easily streamline their browsing workflow and enhance their productivity.
