Hey Germans, please come up with a word that means "the fear of typing `return` vs `shift-return` because you don't know which inserts newline and which sends the message"
You could go with something like Eingabentastenumschalteverwechslungsangst, if you enjoy needlessly long compound words. Doesn't mention newline or messages, though. Sendetastenverunsicherung is a bit looser and closer to something someone would actually use.
