Youtube Keyboard Shortcuts is a Chrome extension that allows users to control Youtube using keyboard commands. By pointing the mouse to a video preview, users can utilize various keys to block videos and channels, like, dislike, save, and mirror content. Additionally, users can click the extension icon in the toolbar to view a list of available shortcuts.

When needing to undo an action, users can hover the mouse over the preview and press the keyboard shortcut U. Furthermore, while watching a video, pressing the home shortcut navigates users to the Youtube Home page, and pressing S saves the video to a playlist. The extension's shortcuts are also functional in fullscreen mode, enhancing user control and convenience.
