How times have changed. I have discovered that we are friends with vi & Klingons, and we are at war with eclipse, netbeans, and the borg.
Eclipse has an emacs mode built in.
Eclipse has a set of Emacs key bindings, but it's hard for me to use because I have muscle memory of features that don't exist in Eclipse (prefix arguments, buffer manipulation, and so on). The Emacs+ plugin is better, but I honestly prefer to use the normal bindings rather then get tripped up repeatedly by fake Emacs.
Or brace styles in C-ish languages. I miss those. And then, tabs or spaces.
