Hi,
I just got a MacBook Pro and saw your site.
Thought I'd try to see if they worked on my computer, but they didn't.

I have a Spaces key in F3 that splits the screens and shows everything that's open.

Are you talking about this thread (https://www.askmehelpdesk.com/computers-beginners/macbook-how-do-you-288627.html)? I'm not sure what you're asking... what isn't working for you?
