Hi everyone,

I’m hoping you can shed some light on why nano does not work for me, please see the attached snippet… In the exercise it says to type ctrl + o but nothing happens, I also tried to exit with ctrl + x or z but no luck . I have pressed the keys as well hoping it will work that way… :relaxed:

Please note I do have a problem with my keyboard ( Ctrl +C does not work…I mean any Ctrl Commands…Sticky keys :grimacing:) I’ve tried fixing it sooo many times but it’s just not having it.

Thanks in advance :v:


Mighty Google helped me with an alternative

^X      (F2)            Close the current file buffer / Exit from nano
^O      (F3)            Write the current file to disk

I still don’t understand why typing it would not work so if anyone knows please I am very curious :smiley:

Update 2 :ok_woman:

The ^ stands for the Ctrl key.

PS: I tried this way but still no luck, the only progress I can make is with F3 and F2 :upside_down_face:

I think that in all their best efforts, the people who create these lessons are giving instructions for humans rather than computers. So they aren’t giving instructions as they would computers. Many of us programming minded people do however think like computers when following instructions and so we follow exactly as they are written.

It also did not work for me when I followed exactly as instructed. So I had to go into human mode and make assumptions.

after you type “Hello, I am nano.” press the enter key
then press ctrl key and the letter O at the same time.
Press Enter key
press ctrl key + x at the same time.
type cat hello.txt


I don’t get any nano menu and nothing works (Mac) :confounded: – Edit: it didn’t work in Chome, so I tried Safari and that worked.
