The DJ Controls for YouTube makes your media keys (previous, pause/play, and next) into global keyboard shortcuts for the YouTubes. Is this real life?

The new DJ Controls for YouTube (pronounced DJ control) is a Chrome extension to control YouTube playing in the background. With it, you can use your media keys to control playback from a different tab or even a different application. You will no longer have to type in the YouTube URL to view a video. You can now control the playback of your videos from the media keys on your computer (F7 for previous song, F8 for play/pause, F9 for next song) to control playback from the YouTube application. Pressing the media keys on your computer will now play a video in the YouTube application. You can also use the media keys to control the playlist in the application. Pressing Ctrl (Cmmd for mac) + Shift + 9 will shuffle and un-shuffle the playlist for you.
