Editing Chorded keyboard (section)

===Historical===
The WriteHander, a 12-key chord keyboard from NewO Company, appeared in 1978 issues of ROM Magazine, an early microcomputer applications magazine.

Another early commercial model was the six-button [[Microwriter]], designed by [[Cy Endfield]] and Chris Rainey, and first sold in 1980. Microwriting is the system of chord keying and is based on a set of mnemonics. It was designed only for right-handed use.

In 1982 the Octima 8 keys cord keyboard was presented by Ergoplic Kebords Ltd an Israeli Startup that was founded by Israeli researcher with intensive experience in Man Machine Interface design. The keyboard had 8 keys one for each finger and additional 3 keys that enabled the production of numbers, punctuations and control functions.  The keyboard was fully compatible with the [[IBM Personal Computer|IBM PC]] and [[IBM Personal Computer AT|AT]] keyboards and had an [[Apple IIe]] version as well.  Its key combinations were based on a mnemonic system that enabled fast and easy touch type learning.  Within a few hours the user could achieve a typing speed similar to hand writing speed. The unique design also gave a relief from hand stress (Carpal Tunnel Syndrome) and allowed longer typing sessions than traditional keyboards.  It was multi-lingual supporting English, German, French and Hebrew.

The [[BAT keyboard|BAT]] is a 7-key hand-sized device from Infogrip, and has been sold since 1985. It provides one key for each finger and three for the thumb.  It is proposed for the hand which does not hold the mouse, in an exact continuation of Engelbart's vision.
