> arrow keys as Apple does it No. NO!!
poster is probably referring to this: https://images.idgesg.net/images/article/2019/11/16in-macboo... The left, right, and down arrow keys all on one level, and the up arrow key alone above the down arrow key. Makes it easy to find the right key by touch alone.
I think the sense that space is wasted by those deadzones above the left and right keys is a powerful motivator of these "hybrid" keyboard designs. I do prefer to have them all half-height if any of them are, as it does make it easier for me to "touch type" the arrows.
