Editing Keyer (section)

=== Inspiration from telegraphy ===
An example of a very simple keyer is a single [[telegraph key]], used for [[Keying (telecommunications)|sending]] [[Morse code]]. In such a use, the term "to key" typically means to turn on and off a [[carrier wave]]. For example, it is said that one "keys the transmitter" by connecting some low-power stage of the [[amplifier]] in a [[transmitter]] to its follow-on stage, through the telegraph key.

When this concept of an ''[[Telegraph key#Dual-lever paddles|iambic telegraph key]]'' was introduced to inventor [[Steve Mann (inventor)|Steve Mann]] in the 1970s, he mistakenly heard ''iambic'' as ''<u>bi</u>ambic''. He then generalized the nomenclature to include various "polyambic" or "multiambic" keyers, such as a "pentambic" keyer (five keys, one for each finger and the thumb), and "septambic" (four finger and three thumb buttons on a handgrip). These systems were developed primarily for use in early, experimental forms of [[wearable computing]], and have also been adapted to [[cycling]] with a [[heads-up display]] in projects like BEHEMOTH by [[Steven K. Roberts]]. Mann (who primarily works in [[computational photography]]) later utilized the concept in a portable [[backpack]]-based computer and imaging system, WearCam, which he invented for photographic light vectoring.<ref>
