The World View window’s default location is under the Assigned list box. Use the World View window to control which portion of the package is displayed in the Package window. The blue rectangle (known as the Package rectangle) represents the package. The green rectangle (known as the Viewing rectangle) represents the currently displayed area in the Package window.
To display another part of the package, use the left mouse button to drag the Viewing rectangle to the area on the Package rectangle you would like to display. To specify a new display area, use the right mouse button to drag out a new Viewing rectangle on the Package rectangle.
