KDE uses “meta” to refer to the Windows key. Emacs uses “meta” to refer to the Alt key. You are correct that GNOME calls the Windows key “Super”.
This causes some confusion, obviously we Linux users don’t want to call it the Windows key, so the best solution is to call the keys “Super” and “Alt”, those are unambiguous.
