Some keyboards have an additional row of keys that perform various functions. Mine for example let's you play/pause/skip media, increase/decrease/mute volume. Go to desktop, open mail, open calculator, open notepad etc. It's great

Oh that's what I use too! :D I got confused by the "double TK" part I think! The "ten key" is the numberpad afaik.
