@AACDuke writes in asking what that mystery key above the '6' is on Apple's keyboard. The iPad doesn't use function keys like the Mac/PC so there isn't a backup 'function' like on keyboards we're used to. The easiest/simplest/most likely idea is that it is just there for aesthetic reasons, like the dummy screw on earlier MacBooks.
But it seems a little silly, even for Apple, to build a key with absolutely no purpose. From a technology perspective they've likely taken the same internals from their aluminum keyboards, meaning it is a live key.
So what do you think that key will do? Will it be unveiled sometime later
