I can't see what the arrow key layout is on the narrower (non-numeric-keypad) version because a hand is over it. It looks like there's a big key where there would be space above the left / right keys on the most recent one. I've got one of the interim ones where the left / right keys are full size so it's difficult to know where they are by touch, and I'm still irritated by that. I hope they haven't gone back again.
