You are just scraping the surface but that's ok. I've been using Vi/Vim for over 20 years and I'm still learning it but to me, that's what makes it so much fun! I learn a new thing (e.g.; `%` for toggling the cursor between matching things like parens) and then try to use that as much as I can for awhile until it's integrated into near muscle memory. Then I get the itch to learn more and so I dive back in.
