"Cherry has launched a Klingon language personal computer (PC) keyboard enabling users to use the Klingon language and fonts on their computers running either Windows, OS-X (Mac) or Linux. According to Chancellor Stalker Zantai Subaiesh of the Klingon Imperial Diplomatic Corps on Earth, "PC users will now be able to work directly in Klingon and interface seamlessly with commercial Klingon systems, bringing Human and Klingon cultures closer together."
Michael Groom, General Sales Manager at Cherry Electrical Products, comments: "The Klingon keyboard is the first step in providing PC input devices for all Federation cultures and will aid communications between Earth and other cultures within the Federation that fall outside the domain of Starfleet command. Of course, this keyboard demonstrates our capability to deliver custom keyboard designs, keycaps and layouts - whether on this planet or elsewhere in the universe!" Key features of the device, part of a broad range of Cherry keyboards, is its space saving, compact design, long-life and comfortable actuation. It is also recycling-friendly.
