Episodes 51, 52, 53, 54, 55, 58, and 59 are all on the topic of copy and paste in Vim. I think that this is one area where Vim is especially confusing, partly because of Vim’s non-standard jargon for cut, copy and paste operations. It’s not the most intuitive copy/paste system, but it’s usable when you get the hang of certain concepts and techniques.
