Emacs keybinds are great. How do you move the cursor up, down, left, and right without them, the arrow keys? My pinky doesn't stretch that far, and if I have to move my hand I'm gonna lose time moving back because I need to find the articulation for my index finger. Vi bindings are even worse: you start typing and the text goes haywire because you're in the wrong mode.
