Interactive Presentation Navigation Styles: In-line
In-line Navigation: Another simple form of navigation is called In-line where links appear in a line, usually at the bottom of slides. Notice that with this style, all link choices remain visible all the time, even as you click around between different slides. They act like a cheat sheet of sorts to remind you of topics covered, or yet to be covered.
Sometimes we use text links instead of thumbnail images. That choice is completely arbitrary of course.
The strip of navigation can go anywhere on the slide, although we generally place it at the bottom to be least noticeable while presenting.
