# Change title of bookmark in Preview

In Preview.app (Mavericks version) bookmarks can be added (Cmd-D) to a PDF file and shown in the sidebar.

The bookmarks all get the same title, which seems to be an excerpt from the first line(s) of the page.

So far, so good, except that in the document I am working on over the next many months, there is a page header on every page and it is the same for 300 pages or so.

The result is that the first text on each page is the same and all bookmarks look identical, except for the page number.

The problem is that I can't find a way to change the title of the bookmark once it has been created, so my side bar contains 20 indistinguishable bookmark titles, only differentiated by the page number.

If I knew the page numbers I wouldn't need the bookmarks, so I am very interested in a way to further differentiate the bookmarks, preferable by changing their title.

Is there a way to do that?

• There does not seem to be a way (at this moment). I have seen this question asked on various other forums as well. Unfortunately, preview seems to add these bookmarks directly into the PDF rather than in some config file, making it difficult to manually alter the contents. – Joost Apr 9 '14 at 15:44
