Use Number Keys To Jump To Specific Times In YouTube Videos

Here’s how it’s done:
1. Load up any YouTube video. You have a wide selection to choose from at our YouTube channel, pcmedianet.
2. Start video playback by specifically pressing the play button at lower left:

What this does is give the Flash Player application focus, and that’s needed for this to work.
3. When the video starts playing, number keys above the letters (meaning not the number pad) now act as time markers.
Pressing 0 (zero) will jump to the beginning of the video. 1 is 10%, 2 is 20%, 3 is 30% and goes all the way to 9 for 90%. And yes this will work whether the video is completely loaded or not.
This actually comes in handy when the Flash player decides not to recognize your clicks on the progress bar (which happens from time to time). Keystrokes always work when the player is in focus.
