Exit nano in terminal. cmd+X is not working

Question

My OS is macOS Catalina.

I open nano version 2.0.6 in the terminal to edit a file. nano first-loop.sh

To exit nano, I have tried Cmd+X and Cmd+SHIFT+X, but none of these two options performs any action.

It is only when I type SHIFT+Esc+X that it reacts. However, most of the times, pressing this would only enable and disable the Help mode. Scarce times when I press this same combination SHIFT+Esc+X is when it asks to save the file: Save modified buffer (ANSWERING "No" WILL DESTROY CHANGES) ?

I wonder why the same command can activate two different actions on this stochastic manner (I have not been able to identify a pattern). I find it absurd that I have to press the same key over and over until it decides to react in the way I expect.

Is there any keyboard combination I can use to be certain I will exit nano?

Many thanks

Answer 1

The solution that worked for me to exit nano was ctrl+shift+X

Answer 2

This is indeed a genuine problem. I see the same. CTRL+x does nothing apart from type an x

My fix was it's keyboard related, use the laptop keyb directly and works as expected
