Vim-problems. I was an Emacs user for ages, and I could use other text editors just fine.
The "Emacs mode" in them usually just meant readline hotkeys: C-p and C-n for previous/next line, C-a and C-e for beginning and end of line, and C-k for delete line. These are the only real movement commands I used in Emacs, and they work in almost anything. Even nano has most of these. SourceGear Products.
