You can rearrange the order of your slides by following these steps:
1. In the thumbnail pane, click the slide that you want to move to a new position in your presentation.
2. Hold down the left mouse button and drag (move) the mouse up or down within the thumbnail pane.
PowerPoint displays a horizontal line between slides to show you where your slide will appear. If you drag the mouse to the top or bottom of the thumbnail pane, PowerPoint automatically scrolls up or down the list.
3. Release the left mouse button when you're happy with the slide's new position.
Hiding and deleting a slide
If you have a slide that you no longer want in your presentation, you can either hide or delete it. Hiding a slide keeps the slide but doesn't display that slide when you give your presentation. You may want to hide a slide in case you need it later or so you can reference the information on this slide with the rest of your presentation.
To hide a slide, follow these steps:
1. Click the slide in the thumbnail pane that you want to hide.
2. Click the Slide Show tab.
3. Click Hide Slide in the Set Up group.
PowerPoint dims your chosen slide and highlights the Hide Slide icon.
To unhide a slide, repeat the above steps.
If you're sure you want to get rid of a slide, you can just delete it. To delete a slide, follow these steps:
1. Click the slide in the thumbnail pane that you want to delete.
2. Click the Home tab.
3. Click Delete in the Slides group.
PowerPoint deletes your chosen slide.
If you press Ctrl+Z or click the Undo icon right away, you can recover a deleted slide.
Designing a presentation with Outline view
Outline view shows the title and subtitle text of each slide in the left pane and the currently selected slide in full size view in the right pane, as shown in Figure 10-3.
The biggest advantage of Outline view is that it lets you rearrange and organize your slides by focusing on their content (title and subtitles). To switch from Slide view to Outline view, click the Outline tab. To switch from Outline view to Slide view, click the Slides tab.
Outline view lets you view just the titles and subtitles of your entire presentation.
