	This JScript example illustrates how to add keys to an fcurve and

// Create a null

var nullobj = ActiveSceneRoot.AddNull();

// Create an fcurve on the posx parameter from the null

var fc = nullobj.posx.AddFCurve();

// Define the number of keys

// Start editing the fcurve

// Add keys to the fcurve

	// Get key using index

	key = fc.GetKeyAtIndex( index );

	// Lock key

// End editing the fcurve and put the undo event onto 

// the undo/redo stack
