If it helps, the Windows/Linux logic is basically:
Ctrl key for triggering actions within an application.
Alt key for navigating the UI of an application via the keyboard.
Meta/Super/Windows key for triggering actions outside of applications (on the OS level).
Well, and Ctrl, Alt, Shift also serve for alternative characters when you’re typing. And some application or OS shortcuts wildly combine modifiers for more complex keybindings. And of course, some applications just didn’t get the note of how this generally works. I won’t claim, it really follows rules, but yeah, it’s not generally complete chaos either.
