If ergonomics was black and white, there'd be only one kind of keyboard that was lawyer-approved here in the Home of the Litigator, Land of the Lawsuit.
edit: Cherry blacks on the Maltron, with a reversed custom keycap for your edification.
There's a LED for all keys that toggle, not just CAPSLOCK, NUMLOCK, SCROLLOCK, but also L-ALT, L-SHIFT, L-CTRL, and R-SHIFT (Other R counterparts do not lock, and have no LEDs).
Another curiosity is the multiple bumps, on hand-positioning keys. The bumps appear to be made of velcro.
