Op Z save in txt file in content mode

I think I’ve read somewhere that you can write a text line when in content mode so that the default state of the op z is in “no save mode”. But I don’t know what the line should be, I’m reffering to the excisting texts “true,” or “false,”.
I’d really like that to be the default save mode when starting my op z. Sure, I can toggle it at start up but forgetting to do so can have devastating outcome :face_with_peeking_eye:.
