This button is fairly simple and straightforward.

1) If the active view that you're in has a parent view or a referencing view, click the button and it will return a categorized-by-view type dialog box to you of where your view occurs.

2) Select one from any of the lists and click the "Jump to View" button. It will then jump to your selected view, highlight where the callout, elevation, or section is, and then make that view active. 

3) If your active view is located on a sheet as its own viewport, the "Jump to Viewport" button will not be disabled. If this button is clicked, your screen will jump to that viewport, and the sheet is located on highlighting the viewport.
