Thank you for the reference. I find the built-in "help" stuff in vi deeply frustrating, because I can't navigate until I learn its navigation commands, and it gives me no way to learn the navigation commands other than by navigating around inside the help system. I'll try again with your suggested reference(s).

With regards this last point though, I don't seem to have expressed myself clearly. My point is that the material covered in this "cheatsheet" page is very, very basic stuff, and if you use vi more than an hour a day then you'll no longer need the cheatsheet within 72 hours. There's little point in having a cheatsheet on the utter basics. Much better to have a cheatsheet on the next level, covering things you only use occasionally, and hence might not remember.

In short, I think we agree.
