Using bookmarks to navigate through a pdf is sometimes easier than using the pages option. Creating them is easy.
With your file open, go to the Window > Interactive panel. There you will see the Bookmark tabs. For this example, let’s say our page is 21 and the title of the page is “I’m here.” Click with your cursor inside the text on the page, either the page number or next to the page title. Click the new Bookmark icon (it looks like a page-turn) and give your bookmark a name. Now, go to to the place in your file that you want to use as the source of your bookmark, highlight it (select it if it is an image or graphic) and then click the name of the Bookmark in the Bookmarks panel.
Remember, when you export the pdf, DO include Bookmarks!Adobe, InDesign InDesign
