 until the Resize pointer appears:   
- Click and hold the left mouse button down.
- Resize the Viewport as desired releasing the left mouse button when satisfied.
Note: The view is 
 attached to the Viewport at the upper left corner of the Viewport. Resizing 
 from the left or right sides has the same effect on the view within the 
 Viewport. The same is true when resizing from the top or bottom of the 
 Viewport.
This action may be undone by clicking 
 on the Undo button on the Common Toolbar.
