Happy Hacking Keyboard

From Wikipedia, the free encyclopedia

The Happy Hacking Keyboard (HHKB) is a small computer keyboard produced by PFU Limited of Japan, codeveloped with Japanese computer scientist and pioneer Eiiti Wada.[1] Its reduction of keys from the common 104-key layout down to 60 keys in the professional series is the basis for its smaller size while retaining full key size. It returns the control key to its original position as on the early 84-key IBM Personal Computer/AT and XT layouts. The current models[2] in production are the Happy Hacking Keyboard Professional Classic,[3] Professional Hybrid (wired/wireless dual connectivity),[4] and Professional Hybrid Type-S[5] (silenced variant of Hybrid) all in either dark or light colorschemes, and either blank or printed keycaps. Professional Hybrid models are also available in Japanese layout.
