Oh, cool! I hadn't heard of the Key Moments/SeekToAction feature before. I'll have to dig in and explore that a bit. Thanks for the tip!
I believe SeekToAction works even if the uploader didn't put chapters in. This was a relatively recent update, to make it fully automatic. So it's presumably doing some audio/video analysis to figure it out. All you need to do is tell Google how to seek your video (so it also works with non youtube videos too).
