Key grabber: make grab_keys introspectable

Browse Source 
To the grab_keys function we pass a list of strings the key
grabber should listen for. In order to make this
introspectable we need to annotate the function correctly. I
followed the instructions for passing arrays [1] and have
chosen the type of the array data looking at [2].
