When creating more complex PowerPoint slides you may need to overlap objects or entirely cover object with others. This can make objects very hard to select as they are underneath each other.
There is an easier way than just clicking with increasing frustration!
Home | Drawing | Arrange | Position Objects | Selection Pane…
Now you have the Selection pane docked to the right of your slide. This allows you to easily see a list of objects on the page and you can select the active object by selecting it in this list. Simple end to frustrated clicking.
