And that this key is called "superkey" is a widespread standard on computers?
Or just linux?
I think the latter. And it might surprise you, but there are computers with no linux installed. I think the vast majority actually. So why the need for insults?
Pretending like the person I'm responding to isn't being willfully ignorant isn't helping. It's pretty simple to guess what "super key" means just from context, if not, it's a very quick (in the op's case) llm query away. Let's be real here.
