Is There a Stage Manager on the Mac?

As far as I can tell, there's no window grouping shortcut on the Mac where you can use a keyboard shortcut to jump between one and another. All of my hot corners have been duplicated so like, if I press the command key, then apparently, like, I can have it do one thing. But I'm not seeing stage manager in here. So hopefully that's on the whiteboard somewhere. It looks really great. And I think that's the thing. It's kind of a mishmash between all of all of the things with some extra stuff on top. We're just gonna all have to cross our fingers and wait and see.
