Some long time ago, probably around 2005, I got convinced that I should use vi for quick edits in the terminal, instead of nano which I had been using for this purpose, for historical reasons.

So I added this simple line to my .bash_aliases:

alias nano='vim'

And to this day I type nano when I just quickly want to edit a file, just out of muscle memory, and I would be very surprised if I would end up in actual nano, not vim.
