Introduction to the Windows 8 Operating System
In many cases, you can use the keyboard instead of the mouse to accomplish
a task. To perform tasks using the keyboard, you press one or more keyboard keys,
sometimes identied as a keyboard shortcut . Some keyboard shortcuts consist of a
single key, such as the 1 key. For example, to obtain help in many apps, you can press
the 1 key. Other keyboard shortcuts consist of multiple keys, in which case a plus
sign separates the key names, such as + . This notation means to press and
hold down the rst key listed, press one or more additional keys, and then release all
keys. For example, to display the Start screen, press + , that is, hold down the

on the computer (Figure 3b). This sign-in screen enables you to sign in to your user
account and makes the computer available for use. Tapping or clicking the user icon
begins the process of signing in, also called logging on, to your user account.
At the bottom of the sign-in screen is the ‘Ease of access’ button and a Shut
down button. Tapping or clicking the ‘Ease of access’ button displays the Ease of
access menu, which provides tools to optimize a computer to accommodate the needs
