To add a slide that contains the content of an existing slide in a presentation, you can duplicate the slide.
Important If you need paste recovery (Paste recovery: Paste options that are available through a button that appears after you paste content. If you click this button, you can choose formatting options for pasted content.), which allows you to keep the formatting of the duplicated slide's content, you will want to copy and paste your slides.
- In the pane that contains the Outline and Slides tabs, click the Slides tab.
- Select one or more slides that you want to duplicate. To select multiple slides, click a slide, and then press and hold CTRL while you click the other slides.
- On the Home tab, in the Slides group, click the arrow next to New Slide, and then click Duplicate Selected Slides.
Note The duplicated slides are inserted directly underneath the lowermost slide that you selected.
