I have some docx documents that contain a lot of footnotes with usually a short footnote text (e.g. "Richard 2010." or "see section xy"). It's much more convenient to have these in the document body in brackets at and in lieu of the footnote reference mark. I don't find a function for this in Word or LibreOffice. I guess I need a macro.
I have seen here a macro that converts comments into footnotes. It's only ten lines. I tried for one night to learn some macro basics and modify some existing macros but failed miserably.
