Lesson two after learning how to quit vim should be that q: opens command history. If I had a dollar for every time that window opened and left me wondering 'wtf, quit damnit', I'd have at least 12 dollars.
My vimrc has:
# Bloody annoying.
nnoremap q: :q
No vim thread is complete without a discussion of how it’s hard to quit.
I'm starting to think that many of us who are so fond of vim are simply experiencing the effects of Stockholm syndrome
