A "key puncher" is a term used to describe someone who operates a keypunch machine or device, typically in the context of early computer systems. This person's role involves manually punching holes into cards or tape using a special machine, which would then be read by a computer for data processing. The combination of symbols "🔑💥💻" can be associated with the description as they represent the key (🔑) being punched with force (💥) into a computer (💻).
