keyer
Morse signal device
A keyer is a device or mechanism that produces or controls signals, particularly in telegraphy and electronics.
In amateur radio, a keyer generates Morse code dots and dashes automatically when paddles are pressed: The electronic keyer made sending code much easier.
In video production, a keyer isolates elements by color or luminance for compositing—a chroma keyer removes green screen backgrounds.
The term also applies to anyone who keys data or operates keying equipment.
