The Presenter Expert’s intuitive four-button design makes it easy to navigate your Keynote® or PowerPoint® presentation. And when you need to move your cursor, a quick flip of a button gives you full cursor control. The powerful 2.4Ghz remote resists interference and lets you control Keynote or PowerPoint from up to 150 feet (50 meters) away. The USB receiver stores inside the presenter so you won’t have to worry about misplacing it. You won’t have to worry about not being able to find the right remote button either, because the Kensington Presenter Expert has backlit buttons.
