The L+Super key (Windows-key) for "Show activities overview" (of GNOME) does not work for me either in Fedora 27. It used to work.
Now in GNOME-config (under right upper corner menu) > Devices > Keyboard, I see Super+S is mapped to "Show activities overview", and it also go there to Activities Overview when I hit Super+S. But trying to remap it to just Super key is not accepted there; it expects the Super key to be just a modifier like Shift and Alt.
Any ideas how to get just the Super key to Show Activities Overview and not needing Super+S ?
Looking with xev, it shows "Super_R". Is this OK? (the windows key is on the left side of the keyboard though)
From xev:
