I happened to notice in a picture that the Apple "German" keyboard had the modifier keys labeled with their symbols, e.g., the option key is labeled as "⌥". (It's confusing as heck that the Apple's U.S. keyboards don't display that, but I'm not going to ask why they did that.)
But unfortunately for me, the German keyboard has a tall and skinny 'return' key, which I'm sure would be frustrating for me. I looked through the keyboard pictures I could find, and the U.S. and Japanese keyboards are the only variants I could find with wide 'return' keys -- and they're also the only ones I found without the modifier symbols printed on them!
Does Apple make a keyboard, for any region, with both a wide 'return' key, and the modifier keys labeled as in the UI?
