Copy and paste slides
1. If you're copying slides between presentations, open both presentations, and on the Window menu, click Arrange All.
2. In normal view , click the Slides tab, and then select the slides you want to copy.
3. Right-click one of the selected slides, and then click Copy.
4. On the Slides tab, right-click the slide in the destination presentation that you want your copied slides to follow, and then click Paste on the shortcut menu.
The pasted slides assume the formatting of the slide they follow, and the paste is complete.
5. To retain the slides' original formatting, click the Paste Options button , which appears under the slides you pasted, and on the button menu, click Keep Source Formatting.
6. If you decide that you want the current design template styles to apply, click Use Design template formatting.
7. If you want to move slides instead of copy them, click Cut on the shortcut menu rather than Copy.
