This is the simplest export from InDesign to PDF as it is all done automatically. In the preceeding book example, the table of contents was generated using paragraph styles. On File> Export (Cmd/Cntrl-E) check both Bookmarks and Hyperlinks. Bookmarks, obviously creates the bookmarks and Hyperlinks makes links in the table to contents to navigate directly to the appropriate chapter beginning.

In this example, the silhouette was used as a hyperlink as well, to connect to www.sherlockholmes.com. This was created with the InDesign Hyperlinks panel.

One other navigational element was included in this PDF and it was done in Acrobat. Note the hand icon as you run the mouse over the text. Clicking it will enlarge the text to fit the window and clicking as you read down will scroll through all the text and pages. This navigation is created with the Article tool. Tools > Advanced Editing > Article Tool. The Article tool was done “by-hand” starting with Chapter One and selecting each column in order throughout the book.

PS Word documents can also be converted to PDFs with Bookmarks and Links.
