Those are all gnome's shortcuts, why you call them ubuntu's?
My Super key presses gives different results than this article. I use POP!_OS18.04 (based on Ubuntu 18.04). For example just [Superkey] + [T] gives me the terminal. Just the [Superkey] gives me all the open applications. There are other differences. [Superkey]+[M] does nothing, while [Superkey]+[v] gives the notifications. I don't know why there are differences but there seems to be some.
Hey ChiefHart, as long as you are running GNOME, the keys should give you the same result. Unless there's a subtle variation in POP! OS.
