Yes, and probably more usable than vi (not talking about vim) and its features are more than enough to edit configuration files.

It has copy paste of a line or an arbitrary chunk of text (I learned that last week! But I often use the copy paste functionality of the terminal emulator anyway), syntax highlighting, undo redo, line numbers, search and replace. Access to these features is efficient.

It's also fast and lightweight. All the characteristics of a good default terminal text editor. Free us from vi! :-)
