Inserting Hyperlinks in a LibreOffice Writer Document

When looking into “Target in Document” the Headings section only shows nonsense. How can I make it show what I want?

I assume you refer to the Navigator’s headings list. In order for it to show what you want, i. e. the documents’s headings, you need to apply the correct paragraph styles to the headings. Those styles also need to have the right outline level applied to them. To apply an outline level to a paragraph style, or see which level it has, right-click on the style in the styles list, select “modify” and go to the “Outline and Numbering” tab. Using this tab’s settings, you can define a paragraph style as being a heading (of any level from 1 to 10), a text body paragraph, or even a list paragraph (by associating a list style to the paragraph style).

These style properties are really a great asset in Writer documents. When you begin to understand how styles shape up your document, that’s when you can really control what you do with it and how it looks and behaves.

Thanks, this answer helped a lot.
It would be great, if the default settings for the Paragraph Styles “Heading 1” to “Heading 6” or so would include the corresponding Outline Level. I think this is a common way editors use Headings as a cross reference or link target in a document. Requiring users to set this first by hand brings up many confusions, especially for users knowing MS Word.

I wholeheartedly agree. Also, I have long been wondering whether the heading style names should be more descriptive. For example, they could adopt the LaTeX levels: (book), part, chapter, section, subsection, subsubsection. This corresponds to common usage. Of course, this de-emphasizes the parallel with HTML headings, which are numbered from 1 to 6, but then again even the HTML heading numbers are out of place! (It would be better if browsers implemented the HTML5 outline algorithm).
