Three iMessage features that most people don’t know about. Number one. Press and hold on the space bar. This turns the keyboard into a trackpad. You can now move your finger around and you could position the cursor precisely where you want it. Number two. Double tap on the space bar when you’re ending a sentence. This inserts a period and a space so you can go on and start your next sentence. Number three. Tap on the time icon in the top left-hand corner. This moves you to the very beginning of your conversation. So how many of these did you already know?
