Your computer's keyboard has four sections: arrow keys, function keys, 
typewriter keys, and the numeric keypad area.

Arrow (Cursor) Keys:

The arrow keys at the lower right of the keyboard move the cursor. Pressing
an arrow key moves the cursor one position in the direction of the arrow. 
Holding down an arrow key repeats the action.

In some programs, the arrow keys perform a separate function.

Function Keys:

How the function keys (F1-F12) operate depends on the program you run. Some 
of these keys perform special functions when you use them in combination 
with the FN key. See "Special Keyboard Functions."

Typewriter Keys:

This main section of the keyboard is similar to a standard typewriter's 
keyboard. However, there are some non-standard keys on the computer. The 
following non-standard keys have special functions on your computer.

CTRL      Use CTRL (control) in combination with other keys to perform  
          specific operations. To use a CTRL key combination, hold down CTRL
          while you press the other key(s).

FN        Use FN (function) in combination with certain keys to control 
          special hardware functions. See "Special Keyboard Functions".

ALT       Use ALT (alternate) in combination with other keys to perform 
          specific operations. To use an ALT key combination, hold down ALT
          while you press the other key(s).

Numeric Keypad:

The keyboard's numeric keypad area is similar to a calculator keyboard. 
Press FN + NUMLK to use the keypad to enter numbers. When you press FN + 
NUMLK, the # icon turns on to show that the computer will recognize the 
keypad area as a keypad instead of normal keyboard characters.

When the 1 icon is lighted, pressing a key on the numeric keypad gives the
values 0-9, decimal (.), plus (+), minus (-), multiplication (*), and 
division (/). Those values are printed in red on the keyboard.

When the 1 icon is not lighted, the numeric keypad copies the other keypad
functions of a 101-key keyboard (alternate cursor keys, HOME, END, PGUP, 
PGDN, INS, and DEL). Some programs require you to use these alternate keys
rather than the separately provided keys. See the diagram below for the
alternate function. Press NUMLK to switch between numeric key entry and the
alternate functions.

To enter one of the alphabet characters when you have turned on the keypad,
press FN while you press the letter you want to enter.

To enter a number from the keypad when the keypad is turned off, press FN
while you press the number you want.

To turn off the keypad area, press FN + NUMLK so the # icon turns off.

Special Keyboard Functions:

You can quickly activate some of your computer's functions by pressing FN 
and the function's quick-key. The following table describes each option.

FN+F1     Sends the F11 keystroke to your application.

FN+F2     Sends the F12 keystroke to your application.

FN+F5     Turns the battery-low bep on and off.

FN+F7     Cycles through the display options in this order:

               Use the built-in screen
               Use an external monitor
               Use both the built-in screen and an external monitor.

FN+NUMLK  Activates the embedded numeric keypad

FN+S      Turns off the built-in screen. Press any key to restore the 
          display.  The key you press is ignored by any application the 
          computer is running. Does not affect an external monitor.

FN+Q      Disables the automatic built-in screen powerdown. Re-enable the 
          option by pressing FN-S.
