A PowerPoint 2007 slide show is set up to work and look exactly like the slide shows that were created in earlier versions of PowerPoint. However, you can customize the way a slide show appears on your own computer. Note, though, that these changes you make to the PowerPoint options apply only on your computer; they don’t affect the way this particular slide show will appear if you show it on another computer.
Choose PowerPoint Options from the Office menu to display the PowerPoint Options dialog box.
Clear this check box if you want to use the right mouse button to move backward in your presentation, or select the check box to display the shortcut menu with navigation and display controls.
Clear this check box if you don’t want the toolbar that contains the Previous, Pointer, Show, and Next buttons at the bottom of the slide-show screen to be visible. Select the check box if you want those controls to be visible.
Clear this check box if you always want to discard any annotations you make during the slide show, or select the check box if you want the option of keeping or discarding the annotations.
Clear this check box if you want the slide show to end when you move past the last slide, or select the check box if, at the end of the show, you want to see the black screen displaying a notice that the show has ended.
