For
each
of
the
keys listed above, an entry in brackets
[]
represents pressing
a single key once with the exception of the [CTRL
xl commands which require
holding down two keys simultaneously.
Also
note
the
<option) format. Where you
see
brackets indicated in
command
lines, enter
any
of the optional commands or file names
listed
or
indicated
in
the
explanation.
The
<angle brackets>
do
not represent any actual Vector 4
command.
Also, note the following symbol:
This
indicates
that
the
text
set
in
from
the
video
screen
marker
_iii_
represents what you will see on your computer.
In some
cases,
the
commands you
enter
will
be
represented the same way.
When
this
is
required,
the
commands you
are
supposed
to
type
in
will be
emphasized
so
that
you
can
tell
them from what the computer is displaying
back
to
you. Note also
that,
while
all
entries in this manual
are
indicated in
UPPER CASE,
it
is not necessary
to
enter
the commands described here in
all
capital
letters.

or
lines, stop the scrolling
of
a
screen display, stop a
p~ogram
operation, or edit your command lines.
The following screen
handling commands
can
be used
