PowerPoint 2011 for Mac has several views that let you edit and view your slides. The most often used view (and this is the default view as well) is Normal view (see Figure 1 below) that displays one slide at a time in the Slide Area. Normal view is great for editing individual slides, and shows PowerPoint's typical tri-pane interface that includes the Slides / Outline Pane, the Slide Area, and the Notes Pane.

To navigate to the next slide you can use the vertical scrollbar on the Slide Area, or the Next and the Previous buttons located at its bottom. You can also use the Page Up and Page Down keys to navigate between the slides.
