Pressing enter in message view sends a message instead of adding a new line
Most IM apps have this as a configurable checkbox in settings actually:
[X] Send messages when pressing enter
In my subjective experience, it tends to be checked by default – unchecking it will give then give other/desired behaviour. At least all IM apps (including NeoChat) seem to agree that Shift+Enter always adds a new line and Ctrl+Enter always sends the message, it’s just what plain Enter should do that is inconsistent.
(Yes, this is my favourite pet-peeve of instant messaging applications.)
