Is there a way in Acrobat to create a "moving" bookmark? When I first read a long PDF document, I usually need to do it in several sittings. In Word documents, I create a line of textm usually a row of XXXXXXXXXs in a bold, red font. As I read the document, I move the line down (Alt+Shift+Up/Down Arrows) keeping track of where I am. I often have several of these delimiter lines in a document. I have created a Word style for them that also assigned a heading level to them so that they show up in the document map. This makes it very easy for me to find where I was and continue. Can I create anything like that in a PDF document?
