Nothing special here: ctrl-click is a standard feature of "array"
fields in a data structure definition. You use it to add elements to
the array. 

Some other click-detections things require more manual work: The
[struct] object has an outlet that will send out messages if a pointer
of that type was selected or changed. Just connect a [print] there to
see what's happening. You can use this with [route ...] to trigger
actions when data structures are changed.
