Nano has already supplanted the great EMacs and Vim as the most popular text editor of all linux distros, for though it has many omissions in functionality it scores over the older, more complete programs in two important respects. First, it is slightly simpler; and secondly it has the text "^ Exit" inscribed in highlighted text on its footer
EDIT : This sees to be going over some people's heads. It's a hitchiker's guide to the galaxy reference.
The Hitchhiker's Guide has already supplanted the great Encyclopaedia Galactica as the standard repository of all knowledge and wisdom, for though it has many omissions . . . it scores over the older, more pedestrian work in two important respects. First, it is slightly cheaper; and secondly it has the words DON'T PANIC inscribed in large friendly letters on its cover.
Well, micro has syntax highlighting and LSP support, and vim is just really efficient at text editing ... though nano's feature set is honestly fine for what it is, I'd much rather it used well-known shortcuts by default.
Asking nano to use the modern keybinds by default is akin to insisting that Emacs run in evil mode by default. If you really must have it do that, set up a shell alias or put something in your .nanorc.
Also, nano has syntax highlighting. No LSP though. It's an editor, not an IDE.
Maybe that explains the size difference I was talking about elsewhere.
