My Macworld colleague Dan Frakes tweeted recently about something he stumbled on when viewing Flash videos on YouTube. Using the J, K and L keys, he found that he was able to skip ahead and back, and pause or play these videos.
Use the following keys to:
J - skip back 10 seconds
K - pause/play
L - skip forward 10 seconds.
These only work with Flash videos; if you load HTML5 videos on YouTube, these shortcuts don't work.
It's worth noting that some websites mention that you can use arrow keys and the spacebar to perform the above actions, but these don't work on Macs.
Why don't you try it out with this video by one of my favorite artists, The Grateful Dead, performing Ripple, from a concert I attended more than 30 years ago.
