Insert a New Text Box
If your slide does not have a text box already, you can quickly add one using the Text Box button. This button is found on the Drawing toolbar at the bottom of the screen.
Alternately, you can add a new text box by choosing Insert > Text Box from the menu.
Tip - If the Drawing toolbar is not visible on your screen, choose View > Toolbars from the menu, and make sure that Drawing has a check mark beside it in the list.
