This extension extends the basic Youtube Hotkeys to give the user more functionality.
With TubingKeys, you get extra Hotkeys that help you browse through Youtube.
You can disable/enable any Hotkeys you want in the Settings.
There you can see which hotkeys are used for which action.
To open the settings, just leftclick on the little icon in the top-right of your browser.
This is still in Version 1.0, therefore you can't edit the Keys yet.
If you have any Suggestions on new Hotkeys, just type in the comments, or contact me via e-mail.
