How can I bookmark the left page of a PDF in Preview? In Preview, Command-D will allow you to bookmark the current page of the PDF for later reference.

How can I bookmark the left-hand page for those times when it's that page precisely that I want to bookmark?

Instead of bookmarks I use Highlights and Notes (alt+cmd+4)

Then I place a Note on appropriate page (left or right) or anywhere.

The advantage is I can make comments in the note.
