I'm calling the "Windows" key "Apple". Because back in ol' times (until 2011) Apple keyboards had an apple on the "Command" key. In France everyone always called the "command" key the "Apple" key anyway; I never heard it called "Command" until I started browsing the English-speaking web 20 years ago; back then I already had called it "Apple" for 10 years anyway.

My Apple //c has two Apple keys, open and closed. It's a pretty good thing, if you ask me.
