Unitedkeys OLED keyboard

for hotkeys I would buy an Optimus Pultius, it's a set of 15 customizable keys. Too bad the price is still too high

I prefer a keyboard like Maximus Optimus, So thoose keys, the hot keys, would tell the keyboard what to show and do on other keys. Like playing a game:

In the Hotkeys i have like "Atack Skills" and "Defense Skills" and if i pressed on, the keys on my keyboard would show and do atack options. =)
