In Baldur's Gate, you could press a key (was it X or L ?) and find out where you were currently located on the map. Does Arcanum have something like that? It would be handy when traveling around the world map. The moving mouse cursor gives coordinates but you have to guesstimate your exact location.
theres one also I believe, Ill check the manual, it may be home or some other key. Im not sure though...
