I want to achieve a formatting like this:
Some text which references (1), for example because (1) might be an example sentence for some grammatical structure which is explained here.
This is auto-numbered text object 1. (1)
The number on the right is assigned automatically. If another auto-numbered object
is inserted before this, it will change to (2), as will all references in the surrounding text.
Some more surrounding text.
How can I insert such numbered sentences and references to them in LibreOffice?
