If you've read and worked with the previous two tutorials on Vim, you're probably getting reasonably comfortable with the editor. At this point, you should be able to get around very nicely. This time around, I'd like to look at some more advanced features and demonstrate briefly how to set up a Vim configuration file, and to get to the shell and use external commands from within Vim.
As you peel back layers of the Vim onion, you'll continue to find new functionality. Some of it may be suitable for your workflow, some not so much. Keep what's useful and discard the rest.

Even though I already knew many of the features you described, I learned some I didn't.
Looking forward for a "Vim 401"!
