I am looking for a keyboard shortcut to show the line numbers in nano editor when navigating up and and down within the file.
I have seen in multiple posts about CTRL+C but this doesn't automatically refresh the line number while navigating.
I remember that in the past I have used such shortcut in Linux terminal and if I recall it was for nano. I also think that it worked out of the box, I didn't have to change any parameters like this article shows: https://askubuntu.com/questions/73444/how-to-show-line-numbering-in-nano-when-opening-a-file
Is there any shortcut to do this? I have Ubuntu 16.04 and GNU nano 2.5.3.
