I've just started using mappoint; went thru the tutorial and have gotten some basics, enough to get a few maps drawn, saved and printed. When you have a map open, how do you scroll slowly to move the map a very small amount? I've tried zooming out, then using the Select tool, include all the locations I want on the map. Then how do I get that centered easily? And how do I zoom in and out just a little to add only a few more streets or locations?
