OPERATION
Keyboard Modes
The
table below describes the typical use
of
the various modes. This use
is
determined by the Operating System
or
by the program currently in
execution.
Unsmft - Lets you input lower case letters, numbers
and
unshift punctuation symbols.
Shift - Lets you input capital letters and shift punctua-
tion symbols.
Hold
down while pressing the
desired key,
or
press the key once so the red
light comes on; while that light
is
on the Keyboard will
output
only Shifted characters.
To
return to the Unshift
mode,
press again.
Caps - Press
the
key once and the red light will
come
on. Typically,
in
the Caps mode, the alphabet keys
A-Z
send
capital-lettercodes only,
and
all other keys are
unaffected.
To
return to the Unshift mode press
~
once
so
the
red light goes off.
Control -
Hold
down the key while pressing
one
of
the alphanumerics; this will
output
the "control"
code assigned to that key.
Note:
The
Shift mode over-rides the Caps mode. So if both
1![~::;l!1~~
lights are on, the Keyboard
is
in the Shift mode.
Control Keys
and
1;'here are
13
Control Keys. Each key outputs a single control code -
regardless
of
what mode the keyboard
is
in. How the Computer interprets
these control codes depends on the Operating System, but here's a
description
of
the typical function
of
each Control Key:
Escape - Usually used to-exit for a subcommand,
ignoring preceding characters
in
the current line.
Tab - Advances the cursor to the next tab position. The
software typically sets
Tab
positions at 8, 16,24,32, etc.
