In the Properties inspector for a document, there is a “Comment” box:
What is the PDF property to which this “comment” field is mapped? (I would test it, but I can’t seem to edit the field from within DEVONthink.)

None. That’s the reason why you can’t edit it.
Checked and yes, it’s not available for PDFs:
> [@Spotlight Comments and Document Comments](https://discourse.devontechnologies.com/t/spotlight-comments-and-document-comments/22738/10):
>
> PDF supports: Author, Title, Subject, and Keywords.

Thanks for the fast reply! I did actually search the forums but apparently didn’t go back far enough. Anyway, this explains the enigmatic comment box.

The “trick” is to search for “PDF comment” and one of the other properties. With “pdf comment subject” and sorted by relevance Bluefrog’s explanation is the fourth result 🙂
