iOS 9 gives you a more intuitive way to control the cursor on an iPad. While editing text such as composing an email or writing a Pages document, you can drag two fingers on the screen to position the cursor. This gives you better control than using the normal one finger with magnifying glass method.
To select a block of text, press and hold two fingers on the soft keyboard to turn it into a trackpad. You can now drag your two gingers on the ‘trackpad’ to expand the text selection.
