...at least I think so! if you already knew, well...sorry! On the iPhone 6s, 3d Touch can be used for text selection. Just force touch a word in the Notes App to select it. You can then drag your finger on the following text to continue selecting. This is triggered by the force of your finger. If you don't press but just rest the finger it will not work. In safari it''s still a bit erratic and not so well refined. For example if you select a single word the magnifying lens, which is not needed in this situation, will appear for a brief moment. It's still nice.
