My main peeve with vim is when it goes into "recording mode" or whatever that nonsense is, when I try to ":q" and hit something by mistake and the screen splits. I still don't know what I did wrong.

And that vim always wants to go back to the last place in the file you edited, even if you edited the file ten years ago and really want to start at the top. The only way I found around that one is to make the .viminfo file chmod 000 so it can't save status.
