Selecting the Position Tab allows you to choose the central coordinates for a selected hemisphere.
The current central coordinate is displayed in the Latitude and Longitude Boxes. Latitude and Longitude may be user edited by typing new values into the windows, or the Get Coordinate with Mouse Button may be selected to allow you to choose new map coordinates with a mouse click.
When choosing coordinates by mouse, it may be helpful to refer to the Status Bar located at the bottom of the main window display, since it will show the coordinates of your current mouse position. Clicking Go changes the view by centering the hemisphere at the displayed coordinates.
