Navigating backward enables you to redisplay nodes in the navigation pane that you have previously viewed. It returns you to the last node you viewed before going to the current node. If you use navigate backward repeatedly, it takes you in reverse order through the sequence of nodes in the navigation pane you have already viewed.
To navigate backwards, do one of the following:
Press Alt + left arrow key..
Click Navigate Backward on the View menu.
Click the navigate backward icon () on the toolbar.
