- ------------------------------------------------------
- Methode KeyboardLED zur Steuerung der Keyboard-LEDs
- (NumLock/CapsLock/ScrollLock-Lichter)
-
- Benutzungshinweise: Man benutze
- KeyboardLED(LEDvalue,"Cmd"), wobei
- Cmd = on/off/switch,
- LEDvalue: ScrollLock=1, NumLock=2, CapsLock=4,
- bzw. eine beliebige Summe dieser Werte:
- AlleAus=0, CapsLock+NumLock=6, etc.
-
- Der folgende Code wurde übernommen von:
- http://www.autohotkey.com/forum/viewtopic.php?t=10532
-
- Um eventuelle Wechselwirkungen mit dem bestehenden
- Code (insb. der Unicode-Konvertierung) auszuschließen,
- sind auch alle (Hilfsmethoden) mit dem Postfix LED
- versehen worden.
