“We thought it was important for the user to be able to invoke every menu command directly from the keyboard, so we added a special key to the keyboard to invoke menu commands, just like our predecessor, Lisa. We called it the “Apple key”; when pressed in combination with another key, it selected the corresponding menu command. We displayed a little Apple logo on the right side of every menu item with a keyboard command, to associate the key with the command.”
Steve Jobs, 1983 - Upon seeing this:

And of course, from 1986 to 2007 …
So the Apple logo on the keyboard managed to hang on for 10 years before Steve Job 2.0 remembered what Steve Jobs 0.9 said …
