 Namenswechsel des Verzeichnis soll dies wiederspielen und eventuelle
 »Gewohnheitsfehler« vermeiden.

+   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.
