  1. Keyer

    A keyer is a device for signaling by hand, by way of pressing one or more switches. Modern keyers typically have a large number of switches but not as many as a full-size keyboard; typically between four and fifty. A keyer differs from a keyboard in the sense that there is no "board"; the keys are arranged in a cluster. A keyer may take the form of a single telegraph key for keying Morse code. In this use, the term "to key" means to turn on and off a carrier wave, typically. For example, it is said that one "keys the transmitter" by interrupting some stage of amplification with a telegraph key. Morse code was an early form of serial communication, which in modern times is usually automated. In a completely automated teleprinter system, the sender presses keys to send an ASCII data stream to a receiver, and computation alleviates the need for timing to be done by the human operator. In this way, much higher typing speeds are possible. Iambic keyers became popular, in telegraphy, in the 1960s. In these, the "dot" and the "dash" are separate keys. In the 1970s, when this concept was introduced to inventor Steve Mann, it was mistakenly heard by him as "biambic" so he generalized the term to include various "polyambic"/"multiambic" keyers, such as a "pentambic" keyer, and "septambic", for use with a portable backpack-based computer system that he invented for photographic lightvectoring.
