You will have to set up an event handler for the OnKeyPress event of the graph and within that function check the key code to see whether or not it is a cursor key. The cursor key has an "extended scan code" that consists of two bytes which is different from the keys that have ascii representations. If you need more information on how to use this behavior I would recommend looking up "key codes" and "OnKeyPressEvent" at http://msdn.microsoft.com
