When you select the Rotation Tab you have the ability to rotate the moon by a set number of degrees. The degree step is displayed in the box at the center of the four directional arrow buttons.

Using
this capability, you can move along the circumference of the lunar surface as
if you were orbiting the moon in a spacecraft, and place yourself directly
above features of interest.
The
degree step may be changed by simply clicking the center box, and entering a
new degree value. The four buttons can
be clicked to change the view by rotating the Moon in the directions shown: Northward (
),
Eastward (
),
Southward, (
)
Westward, (
)
by the displayed degree value.
If you
change the map view to observe areas of the moon that are not visible to
earth-bound observers, you can quickly return the map to the normal view for
your observing location by opening the Time
Manager, and clicking Current.
