Todd A. Jacobs | Rubyist#vim is my code editor of choice, but my fingers still expect some emacs bindings to work in shell prompts. I configure `set -o vi` locally, but frequently access servers or containers where that isn’t the default, so my finger memory sometimes gets bollixed up at the prompt.
On a side note, I also prefer using irb as a tape calculator with history to a GUI calculator app for most things. I can’t be the only #Rubyist who does that either, right?
