This display lets you decide on certain hardware options and indicate your
choice to the 1400 HD. In Setup mode, the function keys perform as
follows:

external color monitor controller.
F7 Lets you choose between an internal clock speed of 8.0 MHz or 4.77 MHz.
F8 Lets you set the date of the real time clock.
F9 Lets you set the time of the real time clock.
Function Keys:
The function keys at the top of the keyboard are program-specific. Their
functions depend on the program you are running. Some of these keys perform
special functions when you start the computer, such as:
CTRL ALT F12 LCD mode. Pressing this key combination tells the
computer to use the built-in LCD screen instead of
an external color monitor.
CTRL ALT F11 External color/graphic mode. Pressing this key
combination tells the computer to use an external
color monitor instead of the built-in LCD screen.
Typewriter Keys:
The main part of the keyboard, below the function keys, is similar to the
keyboard of a standard typewriter. However, when you hold down a character
or number key, the keystroke repeats automatically until you release the key.
This section of the keyboard also contains some keys not found an a standard
typewriter.
ESC The function of the ESC key depends on the program
you are running.
CTRL You use the CTRL key in combination with certain
other keys to perform specific operations. The
combinations available and their functions are
program-dependent. To use a CTRL key combination,
hold down the CTRL key, and press the other key.
For example, CTRL C performs a break or program
interrupt in many programs.
Note: Some software manuals refer to CTRL as CNTRL.
ENTER The ENTER key enters commands and data into the
computer. After you press ENTER, the command you
entered is processed by the program or operating
system you are running.
Note: Some software manuals might refer to ENTER as RETURN or <ÄÄÄÙ.
ALT You use the ALT key in combination with certain
other keys to perform specific operations. The
combinations available and their functions are
program-dependent. To use an ALT key combination,
hold down ALT, and press the other key.
FN You use the FN in combination with cursor keys, INS,
DEL, or ~ to perform the functions labeled in blue
on your keyboard.
INS The function of the INS key depends on the program
you are running. In some programs, this key changes
the typing mode from the normal overstrike (type-
over) mode to the insertion mode so that you can
insert data into a line of text. Pressing the key
again returns the keyboard to the overstrike mode.
FN INS Pressing the FN and INS key combination causes the
alphabet keys to produce only capital letters. (This
function affects only the keys A-Z.) The light on
the upper part of the keyboard indicates when the
keyboard is in the caps lock mode. Press this key
combination once to activate the mode. Press the
keys again to return to the normal typing mode.
DEL The function of the DEL key depends on the program
you are running. In some programs, this key erases
the character at the current cursor position.
FN DEL The FN and DEL key combination reverses the function
of the numeric keypad at the right of the keyboard,
activating a "number lock" mode. When this mode is
active, the numeric keypad provides a calculator-
like pad for entering numbers in application
programs. It includes the numbers, operators
(-,+,/,and *), and punctuation labeled in blue on
the keyboard. The light on the upper part of the
keyboard indicates when the keyboard is in "number
lock" mode. Press the combination again to return to
the normal keyboard mode.
SCROLL LOCK The function of the SCROLL LOCK key depends on the
program you are running. Its use is defined in your
operating system or application program manual.
FN ~ Sends everything currently displayed on the screen
to the printer.
CTRL SCROLL LOCK The function of this key combination depends on the
program you are running. In some programs, this
combination causes a break, halting program
execution.
Numeric Keypad:
The numeric keypad on the right side of the keyboard is arranged the same as
a calculator keypad. Press the FN and DEL keys at the same time to use the
keypad for extensive number entry. When number lock is on, the NUM LOCK
indicator on the upper part of the keyboard lights. The values of the keys
on the numeric keypad are 0-9, decimal (.), addition (+), subtraction (-),
multiplication (*), and division (/) as printed in blue on the keyboard.
Press the FN and DEL key combination again to return to the normal keyboard
mode.
Cursor Keys:
The arrow keys at the lower right of the keyboard are cursor control keys.
Pressing a cursor key moves the cursor one position in the direction of the
arrow. Holding down a cursor key repeats the action.
FN <-- Executes a "home" function. The function depends on
the program you are running. In some programs, "Home"
moves the cursor to the upper left corner of the
screen.
FN --> Executes an "end" function. The function depends on
the program you are running. In some programs, "End"
moves the cursor to the right of the last character
in the current line.
FN (Up Arrow) Executes a "page up" function. The function depends
on the program you are running.
FN (Down Arrow) Executes a "page down" function. The function depends
on the program you are running.
Using and External Keyboard:
The Tandy 1400 HD provides a connection port on the back of the system
for an optional external keyboard. You can connect a Tandy Enhanced Keyboard
(25-4032) or and IBM PC-compatible keyboard. If you wish, connect the
external keyboard, and select EXT during Setup mode.
Be sure that you are familiar with the way the external keyboard works
before you use it with the 1400 HD.
Note: If you are using an enhanced keyboard, it must be set to IBM
XT-compatible mode. The Tandy Enhanced Keyboard defaults to this mode.
