The Home button (See Image - ) is one of the iPad's few physical buttons. It is located on the front of the iPad below the screen.

If you're in an app, clicking it will quickly jump you back to the apps Home screen. If you are paging through your sixth Home screen of iPad applications, pressing the Home button will always take you to the first Home screen. From the first Home screen clicking it again will take you through to the Search page where you can search through all of the data on your iPad.

If you visit Settings -> General -> Home, you can choose to have a double-click of the button bring up the first Home screen, Search screen or iPod. From the Home button menu you can turn on a feature that will pop up a dialog box with iPod controls if you double-click the Home button whilst listening to you iPod music.

The Home button may also be used if you're trapped in a frozen or hung application. You can often escape by holding down the Home button for around six seconds.
