A text box is a framed text which can be easily moved within the slide you are working on.

To insert a text box:

1.Select the slide on the Slide bar.

2.On the Insert tab, click  Text box. When working in macOS, you can also run the Insert > Text box command from the command menu.

3.Enter the text you want to be displayed in the text box.

4.To deselect the text box, click anywhere in the slide outside of the text box or press Esc.

By default, the added text box is inserted in the center of the slide. Once inserted, you can move it to the desired place of the slide manually.
