KEYBOARD SHORTCUTS - Open the extension panel with CTRL+SHIFT+F - Click on the first word of a sentence, tap twice on CTRL to create the start of a sentence HOW DOES IT WORKS? 1. Log yourself into YouTube 2. Open YouTube Studio 3. Select the "Subtitles" category on the left panel 4. Select the video you want to edit the subtitles from (at this step the URL should start by<your_channel_ID>/translations or<your_channel_ID>/translations) 5.

Such a shame this doesn't work for me. Just can't get it to edit the subtitles at all, great idea though

What's the problem exactly? Sometimes you have to refresh the page 2 or 3 times to make the extension work, I don't know yet what happens but I can tell you it works! Feel free to contact me by email so I can help you! Thanks.
