How to add a slide title
Use a built-in slide design
When you use one of the built-in slide designs, you will have a Title place holder where you can add a unique title to the slide.
Restore place holders
If you didn’t use a built-in slide design from the start, you can do the following:
1.To restore all placeholders for the selected slide, on the Home tab, in the Slides group, select Reset.
2.On the slide, type a unique and descriptive title.
Hide the slide title
If you wish, you can make a title invisible on the slide, but still voiced by screen readers.
1.On the Home tab, in the Drawing group, select Arrange.
2.In the Arrange menu, select Selection Pane.
3.In the Selection pane, locate the Title text box, and then click the eye icon next to it.
People who are blind, have low vision, or a reading disability rely on slide titles to navigate. For example, by skimming or using a screen reader, users can quickly scan through a list of slide titles and go right to the slide they want.
