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?
Instead of using Bookmarks, you can use Notes as the replacement to use custom title for bookmarked pages. They serve the same function, with Notes having more versatile usage.


Show the Highlights &amp; Notes in sidebar by pressing Command+Option+4.
To create a note, you can choose Tools &gt; Annotate &gt; Notes or by pressing Command+Control+N.
Select everywhere on the screen and write down the title for your bookmarks (You can also pick the notes background color).


Here’s the screenshot how it looks like:



I’m not sure which Preview version support this,but it should be available after OS X Lion 10.7.
