If you want to add recurring text — or some clever illustration — to each slide within your PowerPoint 2013 presentation, look to Slide Master for simple steps to success. Just follow this procedure:
Call up the Slide Master (by clicking Slide Master in the Presentation Views group of the Views tab) if it’s not displayed already.
Add a text box to the Slide Master by selecting the Insert tab on the Ribbon and then clicking the Text Box button (found in the Text group).
Click where you want to add the text.
Type the text that you want to appear on each slide.
For example, Call 1-800-555-NERD today! Don’t delay! Operators are standing by!
Format the text however you want.
For example, if you want bold, press Ctrl+B or click the Bold button on the Formatting toolbar.
Click the Normal View button to return to your presentation.
Now’s the time to gloat over your work. Lasso some co-workers and show ’em how proud you are that you added some text that appears on each slide in your presentation.
You can add other types of objects to the Slide Master, too. You can add clip art, pictures, or even a video or sound clip. Anything that you can add to an individual slide can be added to the Slide Master.
After you place an object on the Slide Master, you can grab it with the mouse and move it or resize it in any way you want. The object appears in the same location and size on each slide.
To delete an object from the Slide Master, click it and press Delete. To delete a text object, you must first click the object and then click again on the object frame. Then press Delete.
