I forgot - with the current version of the AAO StreamDeck Plugin you don't have to use scripts. You can enter the script code directly in the Actions Key down and Key up fields using type "S:" . 
To avoid stress here's another tipp: the value fields of the Key Down/Up must have a value too (0 or 1, doesn't matter in this case), they can't be empty.
