To edit a master slide, select Master from the View menu and then choose Slide Master, Title Master, Handout Master, or Notes Master . A Master controls the appearance of all the slides or pages in a presentation but does not affect the content. Masters maintain formatting consistency between all slides in a presentation. Even if slide layouts vary within the presentation, the formatting stays the same. For example, if you made the title in SlideMaster appear in Italics, the titles in all of your slides would be Italic.
Masters also standardize the formatting of date, footer and slide numbering information.
Creating a New Slide You can insert a new slide after any slide. To create a new slide, trace to New Slide on the Insert menu or click the New Slide button in the Standard toolbar. Choose the slide layout you want from the dialog box and enter the desired content. To change the order of slides, see Slide Sorter . Formatting the Individual Slide PowerPoint 97 has many features that control the formatting of individual slides.
