        //Detect when the up arrow key is pressed down
        if (Input.GetKeyDown(KeyCode.UpArrow))
            Debug.Log("Up Arrow key was pressed.");

        //Detect when the up arrow key has been released
        if (Input.GetKeyUp(KeyCode.UpArrow))
            Debug.Log("Up Arrow key was released.");
    }
