You want to use this KEY in all Apps or only your own App? – Calvin Mar 15 '12 at 15:29 — Calvin, Mar 15 '12 at 15:29

This is only a walk-around. You can try to listen to key down event. Then for a particular key press, instead of original action, perform your action and tell android that you have handled it.

For example, press "Q", instead of insert an "Q", it should popup a dialog.

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_Q) {
        //popup dialog
    }
    return true; // Handled
}
