A new feature of TOAW IV, however, solves that. Double-click inside the Micromap:
This brings up the Jump Map. The Jump Map is the same scale as the micromap, but shows the entire map (if there is space on your screen). Now you can jump to anywhere on the map by clicking where desired inside the Jump Map. Of course, this map was only a little larger than the max area of the Micromap, so scrolling the micromap might have worked better. But, the bigger the map gets the more useful the Jump Map becomes.
