Exactly the same way as for clicking.
But instead of OnMapClick use Update of your script.
In addition, you can add a check that the mouse position has changed.

Just like on Mouse Click i can get the lat and lon like this  ==>  map.control.GetCoords(out lon, out lat) on OnMapClick();
i was wondering is there any functionality where i can the get the lat and lon when the mouse pointer hovers over the map.
any guidance or suggestions on this would be of great help.
