Shame the keyboards have a copilot key. That doesn't sound so bad until you see that the thing emits a key chord, not a scancode, making it annoying to remap. But you can.

The most annoying part is that the key matrix isn't set up to 3-key rollover with the copilot key like it would be for a real modifier key. (I'd assumed they'd just keep the matrix they used when there was a modifier in that spot. Nope.) Consequently, some key combinations, e.g. ralt-rcontrol-spacebar, don't work. Press them, nothing happens. Infuriating.
