I pinch my nose when I use a Mac and call it the command key. Sometimes you never can tell.

I think I call it this because it's a de-facto super key for me as an Emacs user and the title of it is inescapable.

I think the Apple logo was added to it when ADB was introduced with the Apple IIgs and Mac SE/II. It was eliminated in the new keyboards released in Aug 2007.

The apple keys were on Apple /// and Apple //e keyboards, before the gs or ADB. It's 'open apple' because there was also a filled-in 'closed apple'

Yea, that was why the Apple logo was added to the ADB keyboards. The Apple IIgs had to be compatible with the IIe.

Yuhong is correct, Mac 128 era keyboards have no Control key. Weird. Option also hay the word and no logo. Command is just the clover, no text.

Those don't have arrow keys, they're pretty fascist keyboards. Part of the motivation is to discourage programmers from writing text based interfaces for the Mac.

I believe the addition of the Control key was for the same reason.
