PowerPoint has several useful tools and techniques you can use to manage presentations. If you work in Slide Sorter view, it's easy to copy, move, insert, or delete slides. But there are some tricks. To paste a slide at the beginning of a presentation, go into Slide Sorter view and click to the left of the first slide, and then paste.
If you want to copy slides from one presentation and put them in another, select the slide you want the imported slides to appear after (in Slide Sorter view, click between the slides), and then choose Insert, Slides from Files. The Slide Finder dialog box appears, as shown in Figure 28.12.
