Thanks for that tip! I wandered in here hoping someone had already asked and answered and got my reward. I mostly use emacs for the past 15 years, but I learned vi about 20 years ago and use it regularly at something approximating level 4, but only for vi (not vim) commands -- having no real knowledge of visual mode or some of the extended commands. One of the hard things about learning vim is figuring out how to search for help -- because "enable dot command in visual mode" (and variants) doesn't turn up anything useful right away. I know I've got the right idea (esp. when seen in a tutorial like this one) but there's some setting or plugin or subtle nuance that I'm missing.
