Location markers

I think it’d be great if there were a way to define markers in PDFs and RTFs, so you can quickly return to a point in the document.

My immediate use for this is when I want to check the details of a reference at the bottom of a paper. It’d be nice to mark where I am, and have it instantly return there.

More generally though, it’d be cool to support something like Vim’s markers, where you can define as many marker points as you like in some document.

Anyone have any hacks to do this right now?
