Capital 0 and zero may look alike, but
they have different meanings to a com-
puter. Many
computers display a zero
with a diagonal line
(0) through it.
Make
sure you type the correct letter
or number when you give commands
to MS·DOS.
The SPACEBAR moves the cursor to the
right. But to move the cursor along a line
without deleting any characters, use the
direction keys.
Direction keys
move the cursor right,
left, up, and down. They
do not affect the
characters that are displayed. Some pro-
grams ignore
these keys or do not use
them. In these manuals, the direction
keys are also referred to as the RIGHT,
LEFT, UP, and DOWN arrow keys.
To
correct typing mistakes on the current
line, you use the BACKSPACE key (abbrevi-
ated as BKSP). This key deletes characters
as it moves the cursor to the left.
Control Key Combinations
The CONTROL key (abbreviated as CTRL)
has a special task. It lets you give com-
plex commands to your computer by
pressing only two or three keys. You
must hold down the CONTROL key while
you press another key. That is, you use
the CONTROL key as you would the
SHIFT key.
When you press the CONTROL key and the
S key at the same time, you can stop the
scrolling of the screen display. Then to
continue scrolling, press CONTROL-S again_
When you press the CONTROL key and the
C key at the same time, you can stop a
command.
If you want to start (or restart) MS-DOS,
press the CONTROL, ALT, and DEL keys at
the same time.
