A '''keyer''' is an electronic device used for signaling by hand, by way of pressing one or more switches.<ref name=Mann-2002/>
The technical term '''keyer''' has two very similar meanings, which are nonetheless distinct: One for [[wireless telegraphy|telegraphy]] and the other for accessory [[Human interface device|devices built for computer-human communication]]:
* For radio-telegraphy, the term "keyer" specifically refers to a device which converts signals from an "iambic" type or "sideswiper" type [[telegraph key]] into [[Morse code]] for transmission, but excludes the key itself.
* For computer [[human interface device]]s, "keyer" generally refers to both a single-hand multi-switch and the electronics which interpret the user key-presses and send the corresponding signals to the computer.
