>>Sadly, manufacturers (including Apple that claims to "think different", but in this case thinks exactly the same as PC vendors) don't want to add even a single key, Realistically, it's the opposite - they look to reduce and minimize keys; Home/End/Pg keys, arrow keys, all are being mangled/reduced/moved/killed. Every manufacturer wants to make its own bespoke layout for every model they make seemingly, presumably in a valiant effort to make muscle memory thing of the past :-) . Standards are for wussies!
