Get Started with iPad: The Home Button
The starting point for most of your iPad or iPad mini excursions is the Home button, which is the circular button on the face of the tablet at the bottom, as shown here.
The Home button has the following main functions:
When the iPad or iPad mini is in standby mode, pressing the Home button wakes the device and displays the unlock screen.
When the iPad or iPad mini is running, pressing the Home button returns the device to the Home screen (or, if the Home screen is currently displayed, it displays the Search screen).
Pressing and holding the Home button invokes Siri, which enables you to control many iPad or iPad mini features using voice commands. (If Siri is turned off, pressing and holding the Home button invokes Voice Control, Siri’s predecessor.)
Double-pressing the Home button displays the multitasking bar, which enables you to quickly switch between your running apps.
If your tablet is in standby mode, press the Home button to display the slide to unlock screen, as shown. (This screen appears for up to about 8 seconds; if you don’t do anything, the tablet drops back into standby mode.)
Place your finger on the left side of the screen and slide it to the right side of the screen. This either unlocks the tablet and displays the Home screen or, if you configured a passcode during setup, it prompts you to enter that code.
