Use the key listener to detect key pressed events of course and modify the model-view matrix or call glTranslate to "move" something. I advise you to learn the basic concepts of OpenGL before using JOGL.

Edit.: It can be done in a vertex shader too but I'm not the best person who can speak about that.
