What does this do?

Adds extra hotkeys to Twitch VODs for pausing (k), rewinding (j) and fast-forwarding (l).

• "k": pause or resume video
• "j": rewind by 10 seconds (default)
• "l": fast-forward by 10 seconds (default)

You can configure your preferred amount of seconds by changing the first line of code in the source:

var offset = 10;

Feel free to improve it on Github. I'll accept pull requests.
