Return key in Messages on Mac?
Can anyone tell me if it is possible to hit the return/enter key without sending a message in the Messages application on a MacBook Pro (MacOS Sierra 10.12.6)? I sometimes would like to separate message content using the return/enter key, without sending the message (like on iPhone or iPad), but have not been able to discover a way to do this...
