Using the postage stamp view

A miniature outline of the board appears at the far right of the toolbar buttons. You can use this to determine what your current view is in relation to the entire board. You can change the view by moving your cursor into the postage stamp view and clicking on a different area. Or, you can draw a window within the postage stamp view to zoom to that window. Double-clicking in the postage stamp view has the same effect as choosing Zoom All from the View menu.

The status bar

The status bar is located at the bottom of the design window. It displays the cursor coordinates and system memory. When you select a component, obstacle, pin, text, or track, the status bar displays its name and type. As you move the selected object, the status bar updates  coordinates, its distance from its original location, and other relevant information, such as its angle.
