Yeah that makes sense. I would say that everyone should know enough vi to get by, even if it's not their editor of choice, although I suppose there's _usually_ nano or pico.

After I posted my previous response I realized that I actually know a few emacs keybindings thanks to tmux, even though I've never used the editor. I use a lightly modified vim on my laptop, but I think it's best to learn enough of the defaults (of any application/utility) to speed up your workflow on a new host.
