Types
of
Keys
Keyboard areas are shown in Figure 3-3.
• Function keys
(F1
through F12)
are
pro-
grammable by the user.
• Alphanumeric keys produce a printable let-
I
ter, number, or symbol, just like typewriter
keys. Special keys (Ctrl, Alt, and Shift)
in
this area control computer operations.
• Editing keys are used to move pages onto
the
screen, to move
the
cursor about
on
the
displayed page, and to modify displayed
characters.
• Numeric keypad number keys are active if
Num Lock is on. The keypad
is
typically
used for calculator functions.
NOTE: Some of the numeric keypad keys
have
a second legend; these keys perform
an
editing function when Num Lock
is
off.
Remote keys
Remote keys send signals (printable characters
or
operating messages) to the computer when the
terminal is on line. When remote key signals go
to
the computer, your program then controls their
effect. Forexample, the Backspace key may erase
the character
to
the left
of
the cursor in some
programs, and move the cursor
in
other programs.
Most keys (even alphanumeric keys!) are remote
keys. This means that when the computer controls
the terminal,
tilts manual cannot predict what hap-
pens when you press a remote key. Consult your
software manual.
When the terminal is not
on
line to the computer,
it receives signals from the remote keys and re-
sponds to their commands.
Local keys
Local keys send codes only to the terminal itself.
They cause the same terminal operations regard-
less
