Collapsing and expanding the Navigation pane

The Navigation pane buttons can be collapsed into icons in order to enlarge the Navigation pane.

To collapse the Navigation pane buttons:

1. Place the pointer over the horizontal splitter bar at the bottom of the Navigation pane. The pointer becomes a double-headed arrow.
2. Drag the splitter bar down to collapse the buttons, one by one, into icons that appear in the bottom of the navigation pane, similar to the following figure.

3. Drag the splitter bar up to expand the icons, one by one, back into buttons.
