    hold the alt key type 0176
    it gives the character for degrees as in:
    57ー

    I believe the Northstar 6100i will do either rumbline or great circle courses.

    is a cool web site with great-circle mapping. it knows a lot about aviation, but you can also give it lat/lon and it will show the path between the locations.
    One thing it can do is plot ETOPS exclusion zones, areas where an airplane would be more than minutes from an emergency landing airport.
