if (document.layers)document.captureEvents(Event.KEYDOWN);
document.onkeydown=function(e) {
 var myKey=e?
            document.layers?
             e.which:
            e.keyCode:
           event.keyCode;
 switch(myKey) {
  case 9: alert("TAB has been pressed"); break;
  default: alert(myKey);
 }
};

Stupidly, pre-Gecko Netscape doesn't detect TAB key presses.
