How to use Peek and Pop
The heart of 3D Touch lies in the Peek and Pop functionality. Press down on an email or a web link and you’ll get a peek at its contents. You can also swipe your finger up to reveal an array of options, such as Open Link, Add to Reading List, or Copy with a website link. Let go, and you’ll drop back to where you were. If you decide you want to continue and visit that website or open the full message, simply press down harder to Pop in.
How to quickly send a message or start a call
You don’t need to open the Phone or Messages app to reach out to one of your contacts. Instead, you can just press down on a contact’s photo while in just about any app, and you’ll bring up a menu with options to start a call, send a message or FaceTime. Additionally, you can press down on messages to send quick replies. While in the Messages app, press down on a conversation to peek at it, then swipe up to see some quick reply options like OK, Talk Later, and Thanks! If you have a number you want to turn into a new contact, press down on it to reveal options to add it to an existing contact or make an all new one.
3D Touch the flashlight
One of the advantages of the iPhone 6s is 3D Touch, which enables you to quickly access more options on many things throughout iOS by pressing down gently. You are now able to 3D Touch the flashlight toggle in control center, so you can adjust the intensity between low, medium, and bright light. We use the flashlight every day, so this is a welcome addition to the flashlight toggle.
Close all tabs
Another handy option that 3D Touch offers is the ability to close all of your open tabs in Safari at once. All you need to do is long-press on Done, which you’ll find at the lower right-hand corner. You will see a pop-up that says New Tab, and Close X Tabs, where X is the number of tabs you have opened. Tap on that, and all of your open tabs will disappear at once.
Clear all notifications
Sometimes, your notification area can get out of hand, and you may want to clear it out. Instead of having to clear notifications one at a time, you can now use 3D Touch to help you. If you press on the X at the top of the notification area, you will see the option to Clear All Notifications. Once you select that, all of your notifications will be closed at once.
