At the bottom of the screen you have the choice of Hand mode, Rotate mode, and Arrow mode, as indicated by the obvious icons. It's an either/or proposition--you can only be in one of these modes at once. Most of the time, you'll be in Hand mode. I really see no use whatsoever for arrow mode, but if you do, lovely. Arrow mode lets you input Points and Routes.

In Rotate mode, if you put the cursor somewhere on the map, you can rotate the map. Most Westerners prefer to keep a consistent orientation with North up, but if you want to spin your map around, go for it.
