re-arranging stuff in an Outline is a core Chore of an Outliner, alright.
Especially helpful and thus needed is the possibility to create a new line bringing over to this very new line everything that follow after the cursor.
However, I am not able to achieve that in OmniOutliner. And to be honest: I do not even know where – in the App as well as here in the Forum – what to look up in order to get answers to questions like this one.
Thanks @Nick for your reply. Are you certain you are referring to creating a genuine new line instead of only a linebreak? Ctrl + Enter just creates a linebreak – which I neither meant nor need ;-)
