You can also set a new root by moving back to where you were before, moving forward to where you just were, or for the List view, moving up a level.
To move back, forward, or up one level:
Select View>Back, View>Forward, or View>Up One Level from the menu bar, or select Back, Forward, or Up One Level from the pop-up menu.
The name of the location you are moving back to or forward to is appended to Back and Forward.
