Since I decided not to bother changing the shortcut, I cannot remember. I will as @Aravisian.
I have no idea. I do not use the Zorin Gnome version.
Unlike XFCE, the Gnome keyboard Shorcuts tab from gnome-control-center does not show the existing shortcuts with their commands. So I cannot check it that way on Gnome, either.

The keybinding schema is
Well... I have now found another solution, which I can live with...
Via SETTINGS > SHORTCUT KEYS and then NAVIGATION > SHOW ALL APPLICATIONS this modified from [SUPER]+[A] to [SUPER]+[/] and this works. Again I don't get the zorin menu, but I can now type in the name (partially) of the application and open a program like this (with enter).
In the keyboard shortcuts can't you just search what the super key was defaulted to (activities or app menu) then change it and hit your super key which is a different acpi signal, which would change the binding to right super?
