< Learning Vim, what am i doing?
I first used vi over 30 years ago. I learned how to enter and leave insert mode, how to move around without arrow keys, and how to do inserts/deletes/replaces by word or by line, in the first couple of weeks. I have learned nothing since then, though I still use it once in a while for config file edits.
To be fair... I started using Emacs a few months later, and never looked back.
