Editing Keyer (section)

===Common computer keyer use ===
Computer interface keyers are typically one-handed grips, often used in conjunction with wearable computers.{{Citation needed|date=June 2016}} Unlike key''board''s, the wearable key''er'' has no board upon which the switches are mounted. Additionally, by providing some other function – such as simultaneous grip of flash light and keying – the keyer is effectively hands-free, in the sense that one would still be holding the light source anyway.

[[Chorded keyboard|Chorded or chording keyboards]] have also been developed, and are intended to be used while seated having multiple keys mounted to a board rather than a portable grip. One type of these, the so-called ''[[QWERTY|half-QWERTY]]'' layout, uses only minimal chording, requiring the space bar to be pressed down if the alternate hand is used. It is otherwise a standard [[QWERTY]] keyboard of full size. It, and many other innovations{{Example needed|date=September 2018}} in keyboard controls, were designed to deal with hand [[disability|disabilities]] in particular.{{Citation needed|date=June 2016}}
