Using the latest Help: https://help.libreoffice.org/7.3/en-US/text/shared/05/new_help.html Go to "Index" and type "Find & Replace". This results in only one match: "resetting -- Find & Replace mode". Click this match and a page with a single sentence will open. However, the original file has a lot of contents that are applicable to Writer. https://opengrok.libreoffice.org/xref/help/source/text/shared/guide/find_attributes.xhp But because the file is stored in the "shared" folder, the "<case select="WRITER">" clause is never true and the contents are not shown. There are two ways to fix this: 1) Remove the switch clause from the file; this is an easy fix, but it will keep the file as "Global" instead of "Writer" 2) Move the file to "source/text/swriter/guide/". This is the complete fix, but I'm afraid this will require re-translation of all strings.
