How do I create bookmarks?

I’ve tried in Word to create bookmarks that would show up in Sumatra but have failed (probably due to over-thinking). Also tried in [Polyedit] (http :// polyedit .com/) to no avail.
I use PDFCreator Plus v3.5.1 to generate my pdf files.
Thanks for any info.

I cant tell you how to use Latest Word in all its glory and Polyedit is much too old

Generally you define the headings at each “Level” then specify which levels go to generate the TOC

Each editor has its own way of handling bookmarks and table of Contents
Here is the way that FreeOffice does it
