When you hover the cursor over the numbered circle associated with a row in the Attribute Viewer, you can access three tools that allow you to navigate to that particular feature.
Zoom To Feature: Zooms the map display to that feature.
Pan To Feature: Pans the map display to that feature.
Remove Feature From Results: Removes that feature from the selected set. This removes it from the Attribute Viewer and removes the corresponding marker on the map as well.
