I am also interested in this thing. I took a look at the XCKC Man Page but it
is explained were ... hmmm.... good.

void MainWindow::setKeyboardLED(bool on)
{
   XKeyboardControl kbd;
   kbd.led = 3; 
   if (on) kbd.led_mode = LedModeOn; else kbd.led_mode = LedModeOff;
   cerr << XChangeKeyboardControl(kapp->getDisplay(), KBLed | KBLedMode, &kbd) << endl;
}

I really don't know how to use this thing ! It just does nothing !
Can anyone help me ?

Markus

PS : The cerr always puts out 1 !
