Slide designers love to make quick edits to their slide objects! Impressive slides, though, are created painstakingly and take so much time. For example, you may have to play around with different fill options to make your slides look awesome, or even make umpteen changes to how your slide text appears.
PowerPoint Online does provide extensive commands that allow edits; these command options are found within the Ribbon tabs. Yet, all these tasks involve moving your cursor to the Ribbon, located above the Slide Area and back continuously. While this movement may not result in Carpal Tunnel Syndrome, it helps to know that PowerPoint Online also includes the Mini Toolbar, a floating toolbar that spawns right next to the cursor, and it is also available instantly with a right-click!
