As far as I can tell, this is the first keyboard with 1mm of travel that Apple has made. Before the recent butterfly debacle, their keyboards had as low as 1.2mm travel (on the iMac keyboard) or more. The much-maligned butterfly design got down to 0.5mm travel. So this scissor design with 1mm of travel seems to be something new. The inverted-T arrow keys are not new, but the scissor mechanism itself is, a refinement of previous designs.
