3 “Peek and Pop”
Peek and Pop was mentioned earlier a couple of times. But I wanted to reiterate it here since it’s one of Apple’s main features of 3D Touch. As a reminder, you soft press a message to peek into and press harder to pop it completely open. Peeking and popping is all over the place, so give it a try in your favorite apps and on links. Often you can swipe up while peeking for more options.
