I still use Midnight Comannder's editor (mcedit) whenever I need to edit text in a Linux terminal. I find it a lot more user-friendly than any other terminal-mode text editor.
Vi is downright arcane. You need to hit i before you can type, and you need to hit Escape :wq to save and quit. Fortunately, it's not as bad as classic vi, where arrow keys don't exist, and you need to use ESC then hjkl, and backspace keys don't exist either, and you need to use ESC x.
Meanwhile, in mcedit land, you just hit F9, which is clearly labelled as "pull down", and menus appear. You can see what your options are, and carry out commands. This is why GUIs are awesome, it shows you the possibilities.
