I have a large pdf document. There is a large bookmarks structure in the form of a table of contents. It's helpful and I don't want to mess it.
During reading, I am constantly switching between 4 or 5 specific places, which change let's say once a few hours (depending on reading speed). The document, by its nature, requires such cross-section reading all the time. These are, for example: the text currently read (in progress), the reference text on page 455, table on page 350, a drawing on page 200.
What I'd need is a very quick way to go to these places. Navigating the big bookmarks structure is a very slow option (it takes time to find specific chapter and subchapter and then scroll to a specific page). As mentioned above, I don't want to accidentally mess the structured bookmarks with table of contents.
Currently I am using Ctrl-G to go to specific page and using a pen and paper to write down page numbers currently needed and have them in front of my computer. Perhaps using a set of flat, temporary "quick bookmarks" would be a more comfortable solution. Like e.g. Ctrl+1 go to "quick bookmark 1", Ctrl-2 go to "quick bookmark 2", etc. And of course a way to instantly edit those quick bookmarks, because they change often, like Ctrl-Shift-1 make quick bookmark 1 at current place, etc. 10 "quick bookmarks" would be more than enough. Is there any method to achieve such quick navigation?
