Skip to the good stuff in a YouTube Video

This isn't genealogy, just a something I tried and liked.
Nick Douglas gives three tip in this blog post on Lifehacker, the second of which is particularly worth knowing.
Most YouTube videos have a computer-generated transcript, mostly pretty good, that you can view when its playing by clicking the three dots, to the right of the thumbs-up/thumbs-down buttons and selecting “Open transcript” from the drop-down menu.
Skim through the transcript, it opens to the top right on my computer, or use ctrl-F to search for keywords of interest. Click the line in the transcript to go to that point in the video. Neat.
