The UHK 80 contains these keys. As for the UHK 60, it's a 60% keyboard, which means that only the alphanumeric block is available. There's no dedicated Escape, F-keys, or navigation keys. The advantage is the reduced need for hand movements and a compact footprint. Instead of moving the hands across the various blocks of traditional keyboards, only the fingers move, which is faster once you get used to it. Characters that are not directly available can be accessed through layers.
