It’s great to be able to customize a program according to your workflow — it’s almost like how everyone likes to organize the stuff on their desks, or even the furniture in their rooms. One of the ways that PowerPoint allows you to customize the interface is via adding custom Toolbars — this can be of great help when you use a certain set of commands repeatedly for your tasks. Once you add a new Toolbar though, it’s time to populate the Toolbar with your favorite commands. You can add, reorder, and also remove commands from a Toolbar, as explained in the following steps.
