*/
// Create a null

// Get the posx parameter of the null
oPosX = oNull.posx
// Create array of time-value pairs
aKeys = new Array(      0.00, 5.00,

                        3.00, 8.00,
                        4.00, 9.00,
                        5.00, 10.00 );
// Create an empty FCurve
oFCurve = oPosX.AddFCurve2( null, siStandardFCurve );
// Set the fcurve keys
oFCurve.SetKeys( aKeys );
// Select some keys
SelectKeysInTimespan(oPosX, siSetKeySelection, 2, 4, siInputParameters);
// Get selected fcurves
oFCurves = Application.FCurveSelection;
// Print selected key information
for (var i = 0; i < oFCurves.Count; i++) 
{
        Application.LogMessage( 'FCurve ' + i + ' has ' + oFCurves(i).SelectedKeys + ' keys selected', siInfo );
}
// Produces the following output:
//
//INFO : FCurve 0 has 3 keys selected
