// 
// This example illustrates how to remove a key from an FCurveKeyCollection.
// 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 );
// Get keys
var keys = oFCurve.Keys;
// Remove 3rd key from the collection
keys.RemoveAt(3);
// Print out the contents of the collection
for (var i = 0; i < keys.Count; i++) 
{
        Application.LogMessage( 'Time: ' + keys(i).Time + ', Value: ' + keys(i).Value, siInfo );
}
// Produces the following output:
//
//INFO : Time: 0, Value: 5
//INFO : Time: 1, Value: 6
//INFO : Time: 2, Value: 7
//INFO : Time: 4, Value: 9
//INFO : Time: 5, Value: 10
