YouTube Like-Dislike Shortcut is a free Chrome extension developed by avi12. As the name suggests, this extension allows users to easily like or dislike YouTube videos using keyboard shortcuts. With just a few simple key combinations, users can express their opinion on videos without having to manually interact with the YouTube interface.

The extension provides two main keyboard shortcuts for liking and disliking videos. Users can use Shift+Plus or Numpad Plus to like a video, and Shift+Minus or Numpad Minus to dislike a video. These shortcuts are easy to remember and streamline the rating process.

Notably, the extension ensures that pressing the like or dislike shortcut will only rate the video once. This means that pressing the shortcut again will not change the rating. To un-rate a video, users can use the Shift+0 shortcut.

Furthermore, the extension offers an auto-like feature based on a watch time threshold. Users can customize the shortcuts and the auto-like threshold according to their preferences.

Please note that this extension does not reveal the dislike counters of videos.

Overall, YouTube Like-Dislike Shortcut provides a convenient and efficient way to rate YouTube videos using simple keyboard shortcuts. It enhances the user experience by eliminating the need for manual interactions with the YouTube interface.
