Linux: Nano: how to cut several lines
Self-tutoring about Linux text editors: the tutor mentions selecting multiple lines in Nano.
Here is how it works for me: Ctrl+^ to start the selection, then use the arrow keys to extend it. Ctrl+K cuts, while Ctrl+U uncuts to your present location.
That’s my understanding anyway:)
