vi makes me angry. This was obvious when I installed Debian on a 1999-era iMac and had to edit (probably) x11 conf and had to use vi with JKL; instead of the arrow keys. It made me want to stab something.
That's probably what they were. I was trying to remember exactly, since that was over 6 years ago, and I've never had to use vi like that before or since.
nano makes me happy.
