// 
// This example illustrates how to print selected key information
// Create a new scene
NewScene(null, false);
// Create a null
oNull = Application.GetPrim("Null");
// Get the posx parameter of the null
oPosX = oNull.posx
// Create array of time-value pairs
aKeys = new Array( 0.00, 5.00,
				1.00, 6.00,
				2.00, 7.00,
				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++) 
{
	var keys = oFCurves(i).Keys;
	Application.LogMessage( 'FCurve ' + i + ':', siInfo );
	if (oFCurves(i).SelectedKeys.count > 0)
	{
		for (var j = 0; j < keys.Count; j++) 
		{
			if ( keys(j).Selected )
			{
				Application.LogMessage( '  key ' + j + ' is selected', siInfo );
			}
			else
			{
				Application.LogMessage( '  key ' + j + ' is not selected', siInfo );
			}
		}
	}	
}
// Produces the following output:
//
//INFO : FCurve 0:
//INFO :   key 0 is not selected
//INFO :   key 1 is not selected
//INFO :   key 2 is selected
//INFO :   key 3 is selected
//INFO :   key 4 is selected
//INFO :   key 5 is not selected
