vimtutor, which I believe is installed with vim by default

Edit: My brain apparently inserted an extra word that made it seem like you were seeking said program. Leaving it though for those wondering in the future.

Yeah, but imo the best way to learn vim is to do it as you go. You only really need to know getting in and out of insert and how to write and quit. Once you've got that, if you wanna do something and think there's probably a better way than moving there with the arrow keys, look it up on the Internet, remember the thing, do it a few times and you've learned a new thing about vim. "Surely there's a search and replace function" yeah, is substitute with the s command. "I wanna navigate quicker within lines" use f, t and their capital versions. Combine with the quickscope plugin and you're golden. Learn the stuff you want to use, don't memorize commands you don't need

Tell that to my history teacher...
