Jeffery Adkins: More on the History of Apple’s Command Key. In: Low End Mac. Dan Knight, 15. August 2002, abgerufen am 27. Januar 2024 (englisch): „More on Apple Keyboard History … Back to the IIGS/Mac SE. When the ‘new’ ADB keyboard came out, the Open Apple key became the Apple/Shamrock key. The Solid Apple key became the Option key. Needless to say, this was very annoying when you played a pinball game on a IIGS where the left and right flipper buttons were the Open Apple/Solid Apple keys, and now what used to be the right Apple key (Solid Apple) was now on the left of the keyboard in the form of Option.“
