I use it constantly, because I'm quicker making small edits with it than with vim. I would sorely miss it if it's not installed on a server.
They should have a new tag line:
Nano the plain text editor for non-Vim maybe EMACS users?
Don't get me wrong, I've watched Vim power users do amazing things in that editor but those people are not me and I can't find a good reason to climb that particular mountain.
press i for interactive and make changes then press :wq
:) I have that embedded in my brain after all these years.
nano file_foo
make changes
ctrl-O-Enter - save ctrl-X-Enter - exit
Simpler, I think?
