Ha, real geeks use emacs. Just open up a command line on the pi, install emacs... Well another text editor, probably already got vi or vim but it's awkward. I'dd use nano.
apt-get update
apt-get install nano -y
Nano is a much easier command line text editor. Go to the dir you want it in and type
nano WhatEverFilename
type stuff, press ctrl x to exit, say yes to saving buffer.
