Yes, the Copts do it like the Armenians, and I have seen them touch there hearts or make the Sign of the Cross over their hearts. We use the three finger and go forehead, breast, left shoulder right shoulder. The order of the shoulders is a symbolic reminder that Christ has moved us from the wrong way to the right way. From death to life. The Bible says that at the Judgement, Christ will seperate them...some on the right and some on the left. Those on the right will be ushered in the Kingdom, and those on the left will be told,"Depart from me you who work lawlessness. I never knew you." So, the order in which Copts touch their shoulders in making the Sign is highly significant and full of meaning.
