Most people probably already know how to move the cursor on their iPhone or iPad. It’s essential if you make a typo and want to go back to correct your mistake before you send a text or e-mail, but there is an easier way.
Traditionally, on any iPhone preceding the 6S, the only way to move your cursor’s insertion point is to use the magnifying glass. This is accomplished by touching your finger to the screen and holding it there until the magnifying glass appears. Then you just move the magnifying glass until your cursor is at the spot where you want to fix your mistake.
This method isn’t bad, necessarily, but it can be a little awkward and inexact.
If you have an iPhone 6S or later with 3D Touch, then you’re in luck, because there’s a much better way. Instead of touching the screen until the magnifying glass appears, you can instead deep press on the keyboard until the keys blank out and then it basically works like a touchpad. You just keep pressing and then slide your finger to the desired insertion point.
The difference between the two may be only a second or two at best, but the 3D Touch feels much more natural and exact. Best of all, you don’t have to take your fingers off the keyboard, so corrections can be completed in a more fluid, uninterrupted style.
