#### JScript Example

    //
    // 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
