Jed is a fast, compact editor based on the slang screen library. Jed
features include emulation of the Emacs, EDT, WordStar and Brief editors;
support for extensive customization with slang macros, colors,
keybindings, etc.; and a variety of programming modes with syntax
highlighting.

You should install jed if you've used it before and you like it, or if you
haven't used any text editors before and you're still deciding what you'd
like to use. You'll also need to have slang installed.
