I'm creating a powerpoint deck. There seems to be only one kind of text box -- linear and rectangular. How do I create a text box that "bends" with the circumference of a sphere?
It's Office version specific but here's a general walkthrough:
Select your textbox, go to the Format tab at the top, look for the Text Effects pulldown menu, then to Transform where you'll see all the basic options.
Once you've selected an option you can scale the text box and change the curve to customize the look.
