Hulu key c toggle subtitle is a free Chrome extension developed by rg550black. This add-on falls under the category of Browsers and is specifically listed under the Add-ons & Tools subcategory.

The purpose of this extension is to address the lack of a hotkey for toggling video subtitles in the Hulu web version video player. Despite being requested by the community for some time, Hulu has yet to provide this feature.

Please note that the very first press of the 'c' key might not immediately take effect. It is recommended to try a few more key presses, after which the toggle should work seamlessly.
