When you want to go back to a previous website that you visited in Safari, you don’t want to have to retype the address, or backtrack more than once. You can easily hold down the back arrow at the top of the screen, and it will show a list of recent websites you’ve visited. Then, click the website you want to visit and you will instantly be taken there.
You can also do this if you have websites you visited after the website you are currently on (forward arrow).
Have fun with your iPad!
