I accidentally used Vim the other day. I noticed Vim now has Emacs keybindings -- C-n goes to the next line, C-p goes to the previous line, etc. For a second, I thought that C-x C-s was going to save my file and I was going to be able to exit with C-x C-c. Nope. I had to make the journey over to the ESC key. So close...
