There are several methods for manipulating the appearance and availability of navigation devices. The most showy method involves what we call animated navigation. This process takes advantage of PowerPoint’s versatile animation options for fading navigation buttons, bars, and panels into view as needed. Until faded into view, these elements are invisible to the audience. Once faded into view, they work just as if statically present on the slide. Typically we group such objects, and then animate them as a group. These techniques are covered in the animation tutorial.
