DETAILS
This routine finds the coordinates of the marker that corresponds to the given key. You could use this ability, for example, to extract data needed to place a crosshair on top of a user selected marker. The key for the marker might come from Show_Selection_Element() or Find_Contents() , or it might have been saved by your program when the marker was created (via Insert_Marker() ).
