Did you know your iPad has a hidden trackpad for moving the cursor?
Press and hold two fingers on your iPad’s virtual keyboard. When the keyboard characters disappear, slide your fingers along the screen. The cursor moves with them.
This is helpful for highlighting a section of text (as in image above) or editing email and documents.
Note: The iPhone has this feature but it took me a few times to get it to work; I just kept getting random characters on the screen. It eventually worked when I placed my fingers in the blank space under the spacebar.
