If you play around with your PowerPoint Slide Masters, you may inadvertently delete a layout placeholder you need in your PowerPoint presentation. Suppose you deleted the footer placeholder from a Master and now you want it for your presentation. No problem!

1

Switch to Slide Master View.

Click the Slide Master button in the Presentation Views group on the Ribbon.

2

Select the Master with the missing placeholder.

Soon, the missing placeholder will be right back where it started.

3

In the Slide Master tab on the Ribbon, click the Master Layout button (in the Master Layout group).

This calls up the Master Layout dialog box.
