Great video that shows the console text editors Pico, Nano, Vi and Emacs on Mac OS X.
Many Mac users don’t know how powerful the console terminal can be, but since it is BSD based, it has a very broad set of commands available on the console.
If you need a text editor like Joe, then you can install it from the THE GNU MAC OS X Public Archive using this as a download page: PROJECT DETAIL for Joe’s Own Editor.
