The O'Reilly Network just posted a vi tutorial by Wei-Meng Lee. As much as I can't stand vi, I've needed an article like this for a long time. There are certain situations in which neither BBEdit nor emacs are available -- a newly-installed Solaris system, for example -- or when I don't want to deal with emacs' annoying backup files, and I have to resort to vi at those times. I've learned enough to get by with vi, but now that I've read the article I'll be a bit more comfortable in it.
