A Chrome extension which helps you to control a Youtube video using keyboard shortcuts even when the browser window is not active.
Follow the steps given here:
###Load the extension
- Extensions that you download from the Chrome Web Store are packaged up as .crx files, which is great for distribution, but not so great for development. Recognizing this, Chrome gives you a quick way of loading up your working directory for testing. Let's do that now.
- Visit chrome://extensions in your browser (or open up the Chrome menu by clicking the icon to the far right of the Omnibox:
and select Extensions under the Tools menu to get to the same place).
- Ensure that the Developer mode checkbox in the top right-hand corner is checked.
- Click Load unpacked extension… to pop up a file-selection dialog.
- Navigate to the directory in which your extension files live, and select it.
Alternatively, you can drag and drop the directory where your extension files live onto chrome://extensions in your browser to load it.
If the extension is valid, it'll be loaded up and active right away! If it's invalid, an error message will be displayed at the top of the page. Correct the error, and try again.
Use the following keys for controlling a youtube video running in chrome, from anywhere on the desktop.
- Command+Shift+7 : Previous
- Command+Shift+8 : Play/Pause
- Command+Shift+9 : Next
- Command+Shift+6 : Skip Ads
(Use Ctrl instead of Command for non-apple products)
You can check this options in the Extension Shortcut 
in the top right corner of a Chrome Window.
The Shortcut Keys are specified in the manifest.json file in the project.
##Contributing to youtube-shortcuts We are open to suggestions for new features that can be added to the extension to make the life of a Youtuber easy.
