Keyboard Shortcuts to Close Other/Right Tabs is a Chrome extension developed by Michael Fester. This free extension falls under the category of Browsers and the subcategory of Add-ons & Tools.

The main purpose of this extension is to add convenient keyboard shortcuts for closing and pinning tabs in the Chrome browser. With just a few simple key combinations, users can quickly perform actions such as closing all tabs except the current one (Alt-Shift-O), closing all tabs to the right of the current one (Alt-Shift-R), and pinning the current tab (Alt-Shift-P).

These shortcuts provide a faster and more efficient way to manage tabs, especially for users who prefer keyboard navigation over mouse clicks. The extension is easy to install and use, making it a handy tool for those who want to streamline their tab management workflow.

Please note that this extension does not include additional shortcuts for moving tabs, as another extension called "tabloid" already provides those features. The reason for this limitation is that Chrome extensions currently have a maximum limit of four shortcuts.

Overall, Keyboard Shortcuts to Close Other/Right Tabs is a useful Chrome extension for users who want to enhance their tab management experience with convenient keyboard shortcuts.
