I would assume that the key repeat happens whenever the LED is changed *and* I happen to press a key at the same time. This event happening is IMO independent of the led-delay option, as the LED state could change either by a delay-induced LED_OFF, or by a new packet arriving. > I've only tried it with >USB keyboards but that seems to be required for it to work smoothly >(--led-delay 1 is fine.)
