You have to do something like the following in your implementation of public void keyPressed(KeyEvent e){} Don't do it in keyTyped because that is for higher level key events. either:   if ((keycode==KeyEvent.VK_NUMPAD7) && (keyevent.isAltDown())) doThis(); or if ((keycode==KeyEvent.VK_NUMPAD7) && (modifier == InputEvent.ALT_MASK)) doThat(); as in the following demo code which pretty much covers everythiing you can do with a key event except the consume () methods.  You can check out exactly what happens with every key event here and test your keyboard out. I noted that if I pressed the ALT key by itself and released it then pressed SHIFT that nothing happened. That was strange... I am sure we could all find quirks in our keyboards. /* WhichKeyDidYouPress.java * @author: Charles Bell * @version: Aug 18, 2001 * Copyright � 2001 QuantumHyperSpace.com * <[EMAIL PROTECTED]> * * This program is free software; you can redistribute it and/or modify * it under the terms of the GNU Library General Public License as published * by the Free Software Foundation; either version 2 of the License, or * (at your option) any later version.
