Using Key Combinations:

You can also control computer functions by using key combinations.  To use
a key combination, press and hold down the first key.  Then, press the
other key(s) in the sequence indicated.  For example, pressing and holding
down FN and then pressing F7 turns off the computer LCD and backlight.
Pressing any key turns the LCD and backlight back on.

Special Key Combinations:

There are special key combinations, using the keys labeled in blue, that
can help you save battery power as you use your computer.  These key
combinations override the Setup program and Power program parameters.

FN + F1 (Reverse) With this key combination you can vary the contrast of
characters and the background.  Choose the setting best suited to the
software you use.

FN + F2 (Video) This key combination lets you switch between the computer's
display panel and an external video display.  You cannot use both displays
at the same time.

FN + F3 (Speed) You can press this key combination to select the computer's
speed (20MHz or 10MHz).  The power indicator lights orange when you select
10MHz.

FN + F4 (Disk) This key combination causes the hard disk controller to turn
off until accessed.  No special keystrokes or commands are needed to turn
the disk controller on again.

FN + F5 (Spkr) This key combination enables and disables the speaker.

Note: This will not turn on the speaker if you turned it off in Setup382.

FN + F7 (Display) You can press this key combination to turn off the
backlight and the LCD.  Any keyboard entry you make turns the backlight
and the LCD back on.  You cannot use this key combination to turn off an
external video display.

FN + F9 (Serial) This key combination enables and disables the serial
ports.  Both serial ports are turned on until you press the key
combination.

FN + F10 (standby) This key combination puts the computer in a standby
mode.  The hard disk, LCD, backlight, and floppy disk controller are turned
off until you make a keyboard entry.

Keyboard Functions and Information:

Your computer's keyboard consists of four sections: the arrow (cursor)
keys, the function keys, the typewriter keys, and the numeric keypad area.
The functions of many of the keys depend on the programs you use.  Refer to
your software's documentation for more information about the functions of
keys.

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 automatically repeats the action in some
programs.

Function Keys:

The operations of the function keys (F1,F2,F3, etc.) depend on the programs
you use.  When used with the FN key, these keys perform special functions
for your computer.  See "Special Key Combinations."

Typewriter Keys:

The typewriter keys on your computer are similar to the keys on a standard
typewriter.  However, there are some non-standard keys on the computer.
The following non-standard keys have special characteristics on your
computer.

* FN--Use the FN (function) key in combination with certain keys to control
special hardware functions of the 3810 HD.  See "Special Key Combinations."
* ALT--Use the ALT (alternate) key in combination with other keys to
perform specific operations.  To use an ALT key combination, hold down ALT,
and press the other key(s).

Note: In some programs, the right and left ALT keys are not interchangeable
and might be used to perform separate functions.  Your 3810 HD has only a
left ALT key, but you can press FN + ALT to emulate a right ALT key
function.

* CTRL--The CTRL (control) key is used with other keys to perform specific
  operations.  To use an a CTRL key combination, hold down CTRL, and press
  the other key(s).  Some programs require the right and left CTRL keys of
  a 101-key keyboard.  The 3810 HD only has a left CTRL key, but you can
  press FN + CTRL to emulate the right CTRL key function.

Numeric Keypad Area:

The keyboard's numeric keypad area is similar to a calculator keypad.
Press FN + KEYPAD to use the keypad for extensive number entry; the KEYPAD
indicator lights green.  If the NUMLK indicator is not lit, press NUMLK.
The values of the keys on the numeric keypad are 0-9, decimal (.), minus
(-), multiplication (*), and division (/).  These values are printed in
red.  Press FN + KEYPAD again to return to the normal keyboard function.

You can also use the keyboard's numeric keypad area to emulate other keypad
functions of a 101-key keyboard.  If you turn off the NUMLK indicator while
the keypad is active, the numeric keypad area provides alternate cursor
keys, HOME, END, PGUP, PGDN, INS, and DEL.  Some programs require you to
use the keypad area versions of these keys rather than the separately
provided keys.  Press NUMLK to switch between numeric key entry and the
alternate functions.

Note: The 5 key has no alternate function.

Reversing the CTRL and CAPS LOCK keys:

The 3820 HD's keyboard comes with the CTRL and CAPS LOCK keys in their
standard positions.  However, you might want to reverse the positions of
these keys.  To do so, follow these steps:

1. Exit any program you might be running and turn off the computer.
2. Remove the two screws from the compartment cover on the bottom of the
   computer.  Then, remove the cover.
3. Use a small pointed object, such as the tip of a pen, to set the
   position of the DIP switch.

* Set the switch to 1 to reverse the CTRL and CAPS LOCK key positions.
* Set the switch to OFF to restore the standard CTRL and CAPS LOCK key
  positions.

4. Replace the compartment cover and reinstall the cover's screws.

5. Remove the CAPS LOCK and CTRL keytops using a keytop puller.  Then,
   reverse and re-install the keytops.
