I am just starting off with iOS development. I am trying to add action to a button and it is mentioned on apple developer site that "To Control-drag, press and hold the Control key while you drag from the button to the implementation file in the assistant editor pane." But am not able to do this. What is control key? How can i do this? When I try to add control drag, entire button is getting dragged and am not able to see any control-drag arrow. Thanks a lot for your time.
