The status bar along the bottom of the Office 2016 window gives you information about the file you're working on. The Word status bar, for example, tells you which page you're on, how many pages are in your document, and several other things. In PowerPoint, the status bar tells you which slide you're looking at. It also presents the view buttons and Zoom controls.
To choose what appears on the status bar, right-click the status bar. You see a drop-down list similar to the one shown. By selecting and deselecting items in this list, you can decide what appears on the status bar.
Right-click the status bar to customize it.
