The returnKey
command sends a statement typed into the Message box to the current card.

command to the current card when the user presses the Return key unless the insertion point is in a field, in which case HyperCard sends returnInField

message as follows:
Any return-separated list of built-in commands, user-defined handlers, or keywords that are part of a message or function handler.
