Tap to the Top
While you using Safari, you can automatically return to the top of the page by tapping on the status bar (highlighted in yellow), which shows the time, network strength and the battery information. In addition your tap will display the search bar (where you can type keywords, allowing your chosen engine to scan the web) and the URL address bar (here you type the address of the website you would like to visit)
Tap to start and no need to use www
In the URL bar, taping here begin typing, no need to delete the existing address, if there is already one in there. And no need to add the www. to your address, as this is added automatically.
