A navigation tool permits a presenter to navigate through a presentation, while easily introducing supplemental material into the presentation. Presentation slides are represented as thumbnails on the screen of the presenter's monitor, and are preferably arranged in rows and columns. The rows may indicate a main narrative sequence, and the columns may include thumbnails of slides representing supplemental or background material. The presenter may proceed from one slide to the next using conventional mouse/cursor technology or a remote control device. To this end, a navigation tool is introduced permitting the presenter to easily proceed along a row or a column simply by simply selecting the correct button. A special button is dedicated to making larger jumps back to the main narrative.
