the above is a cheat sheet for the vi terminal-based text editor. it is evil in it's powerful complexity. amongst geek ideology wars, vi is often pitted again emacs. the emacs camp backronyms vi to mean "vicious interface"
my intention in posting this is to communicate the idea that this cheat sheet is, in effect, the GUI of vi, and that that is indeed vicious.
editing crontab in vi is a pita.
Update:
Ok that wasn't so hard... ;)
