If ever we had to present a quite extensive work we will certainly proven it can be useful markers to lead quickly to any section or chapter of it. These Bookmarks are usually located in the rate of work, but is also good to use internal links in the main text.
If the document in question is a PDF There is a very good application for this task, called JPdBookmarks. Based on Java, will allow us create and edit bookmarks Addition to changing the appearance (font and spacing) the structure and hierarchy of these. You can even add links to web sites with internal links, so that when you click on a link that will lead simultaneously to a website and a section of the document.
JPdBookmarks can be used both from GUI or from the command line, although we must bear in mind that to do so in the latter way will not have access to more advanced features.
