About hyperlinks
You can add hyperlinks to pushpin balloons and then access those hyperlinks from the map, an open pushpin balloon, or a Web page saved from the map. You can add hyperlinks in several ways: by importing them from a source data file; by manually typing them in balloon notes; or by having MapPoint automatically create them for a pushpin set.
You can have multiple hyperlinks in a balloon, but only one can be associated with a pushpin. Associating a hyperlink tells MapPoint which hyperlink you want called from the map or from a Web page saved from the map when the balloon is not open.
