There's a guy on Youtube who does programming language tutorials/demonstrations. Like he starts out with C++ and in one hour you're at object inheritance, crash courses I guess is the term for them.

He did one video that was as much a Vim tutorial as a tutorial for this language. "Press 3k, then enter, then i, and type "std::out("whatever C syntax is")" and then hit escape and..."

For teaching something like a little bit of Python or a little bit of Bash or whatever, I'd rather use Nano, because you can learn how to use it in seconds. Vim is an amazing tool but lord don't try to cram a Vim tutorial into another already technical tutorial.
