Is it possible to find out about saving the page?

Question

HTML

I understand that the question is probably strange, and maybe even stupid, but is it possible to know that the user has saved a web page?

Answer 1

through the processing of keyboard events, but the chances are still small.
if he saved it through ctrl + "s" then yes,
but through the context menu - you can guess with a low probability what exactly was selected - saving, printing, or something else.

Answer 2

No.

Answer 3

you can partially try to track user actions, but no one will give guarantees
