Basically copies the like/dislike shortcut from YouTube Music, which means:
• Shift+Plus (on the number row) to like a video
• Shift+Minus (on the number row) to dislike
• Numpad Plus to like
• Numpad Minus to dislike
• Pressing the like/dislike shortcut will only rate the video once, i.e. pressing again won't un-rate it
- To un-rate, use Shift+0 (on the number row)
- This extension can access your data on some websites.
