Use the World window to control which portion of the design appears in the active window of MultiView Navigator's Tools window. The blue rectangle represents the area of the chip. The red rectangle (known as the Viewing rectangle) represents the part of the design you see in a tool window.
To move the displayed area to another part of the design, click and drag the red rectangle to the area on the blue rectangle you want to see. To specify a new display area, right-click and drag out a new Viewing rectangle on the blue rectangle.
