It's not a hardware interrupt at all, and needs to be specifically programmed into the text editor.

It's just that that was the de-facto standard before Ctrl+C and Ctrl+V replaced it. Back then, Ctrl+C was the break key, so it wasn't usable.

Even in Windows today, you can still use Ctrl+Insert/Shift+Insert/Shift+Delete in text edit or rich edit controls. Libreoffice even supports it.

Even today it's the only way to go in Git Bash which is pretty common on Windows dev machines.
