Set by the 3 radio buttons to one of 'none', 'input', or 'return'.

• None: No output port.
• Input: A copy of the input msg is sent to the output.
• Return: The node listens for output from an event-return node receiving a msg._eventOriginator property having the same ID as this node. This allows for sub-flows and loops to be created.
