If you have an object - text or writing - that is in the powerpoint and you can't easily find the object to move it or edit it, you need this tip. First, press escape so you are sure you don't have anything selected. Then press the tab key and you will see that the program will toggle you through all of the pieces that are on your slide.
I wish I would have known this trick earlier! Instead, I was moving the pieces around to find something that was hidden or not easy to select.
