This shows my own ignorance, but did you know the Midnight Commander I talked about recently (If you've never tried Midnight Commander…) also comes with it's own fully featured editor? I've been using MC for years and never knew this!
To edit a file with the Midnight Commander editor, invoke it with the
% mc -e [filename]
The key commands are similar to Midnight Commander's file management mode and are presented along the bottom of the screen, and a convenient bar along the top lets you know the current line and character position of your cursor amongst other things. Hitting
[F10] brings up up an easy to use menu system.
I won't be giving up on my beloved Vim and nano editors any time soon, but using an editor with a blue background, grey text and menus is a nice DOS nostalgia trip!
