If you open vim the first thing you will see it’s a text describing how to close it. Not saying other things are easier for a new user but closing is pretty simple. EDIT: if press ctrl - c vim will show you what you should press instead
And the whole time you have nano open it shows you all the shortcuts how to save and close at the bottom, so no, closing nano is not harder.
Then you press ctrl+g for help and it tells you:
Shortcuts are written as follows: Control-key sequences are notated with a ‘^’ and can be entered either by using the Ctrl key or pressing the Esc key twice.
:D
Actually TIL about pressing esc twice.
I had to look up the upside down V meant Ctrl, which makes sense to me now that I know, but I had to Google that.
