This routine finds the coordinates of the line that corresponds to the given key. You could use this ability, for example, to extract data needed to construct a line parallel to an existing line. The key for the line might come from Show_Selection_Element() or Find_Contents() , or it might have been saved by your program when the line was created (via Insert_Line() ).
