• Alphanumeric keys for typing letters, numbers, punctuation, and
• Control keys for performing certain actions: <Ctrl>, <Alt>, <Esc>, and
the Windows key
• Function keys, labeled <F1>,< F2>, <F3>, and so on, for performing
• Navigation keys for moving the cursor around in documents or
windows: <Home>, <End>, <Page Up>, <Page Down>, <Delete>,
<Insert >, and arrow keys
• Numeric keypad of numbers grouped together like those on an adding
machine (the numeric keypad on most laptop computers is integrated
into the alphabetic keys).
Backlit keyboards provide visibility in dark environments by illuminating
the symbols on the keys using LEDs present below the keyboard. You
can turn on the backlight manually or configure the backlight to turn on
automatically when your computer is placed in a dark environment.
