I know it's nearly 2 weeks early, but nonetheless, let's all compile a list of 3D Touch shortcuts before our phones arrive:
Feel free to add your findings.
- force-touching anywhere on the keyboard activates trackpad
- force-touching app icon gives you quick access to various features of the app
- force-touching the left edge of the screen and sliding lets you switch to the previous app
- force-touching anywhere in the Notification Center clears all notifications
Feel free to add your findings.
