How to Add Bulleted Lists to Diagrams in PowerPoint 2007
Some PowerPoint diagram shapes have built-in bulleted lists, but no matter whether a PowerPoint shape is prepared to be bulleted or not, you can enter bullets. Select a PowerPoint shape on the diagram and, follow these steps to enter or remove bullets:
Click the (SmartArt Tools) Design tab, and click the Add Bullet button.
When you click inside the shape, the first bullet appears. Enter the bulleted items directly into the shape (pressing Enter as you type each entry) or click the Text Pane button to open the Text pane and enter bullets there.
To remove the bulleted items, click before the first bulleted entry and keep press Delete.
You can also start in the Text pane and press the Delete key there until you’ve removed the bulleted items, or drag to select several bulleted items and then press Delete.
