How do I change the Google Maps draggable property for the map (not the marker)?

Question

In the Google Maps v3 reference, I see there is a method setDraggable(boolean) which can be applied to a map marker.

However, I want to set setDraggable to true on the map, not on a map marker.

I have set the property draggable to false in the mapOptions, but I don't know how to set this to true later...  map.setDraggable(true) does not work:

    // object literal for map options
    var myOptions =
    {
        center: new google.maps.LatLng(37.09024, -95.712891),
        zoom: 4, // smaller number --> zoom out
        mapTypeId: google.maps.MapTypeId.TERRAIN,

        // removing all map controls
        disableDefaultUI: true,

        // prevents map from being dragged
        draggable: false,

        // disabling all keyboard shortcuts
        keyboardShortcuts: false,

        disableDoubleClickZoom: true,

        // do not clear the map div     
        noClear: true
    };

    map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);

    map.setDraggable(true); // does NOT work!

Try:

map.setOptions({draggable: true});
