Canon Cat Reference Manual page 51

The Cat keeps
a
tab stop at the
right
margin
as a
kind
of
backstop
to
preventthe cursorfromrunning
to the
next
line
with
one tab
character. This
means
that when
the
cursor is
beyond
the last tab stop
you've
set,
there is
still
an
invisible
tab stop
at
the
right margin.
A
real tab stop can
also be set
at the
right
margin.
Decimal Tab Stop
Decirlral
tabs are used
to align
columns along their
last
characters
or
decimal points. The cursor
stops at
a
decimal
tab
as
it
would
at
a
normal
tab, but further typing
causes
characters
to
emerge
to
the
left of
the cursor
while
the
cursor
itself
stands
still
at the decimal tab stop. Normal
forward-moving typing
resumes
when you
tlpe
areturn,
a
tab, a decimal
point (a
period
in
the
United
States, but
varies
by
country). Normal forward
typing
also resumes
when the tab
character compresses
to
a single
character
position.
Using
One
Paragraph
As the
Model
for
Those Above
It
If
you extend
the
highlight
and then use
[SET/CLEAR
TAB],
all
paragraphs
touched
by
the highlight take on
the tab
setting of
the last
highlighted
paragraph.
Further tab
set-
ting or clearing
applies
to all highlighted
paragraphs.
If
the tab settings
of all
highlighted paragraphs already
match,
tab
setting or clearing immediately applies to all
of
them.
PARAGRAPH STYLE and Tabs
Tabs are
designed
to work in
the
Left
Flush paragraph
style.
If
you
use
a style other than L,eft Flush,
it
will
affect
the appearance
of
tabbed
text
as
follows:
Centered
or Right Flush text with
tabs
still
appears
in
centered or
right flush
style, but,
in
order to
preserve the
proper
spacing between
printing
characters, tabbed text
moves to
the
center or to
the
right
margin. The ruler
is
not
affected by this operation,
so the tab stop
indicators
on
the
ruler no longer line up
with
the tabbed
text on
the
display.
Justified text
with
tabs
appears
justified,
but,
in
order to
spread the
line evenly
and
bring
the
rightmost printing
character up
to
the
right
margin, half-spaces
will
be
in-
serted
next
to
space characters
in
the
text
between the
rightrnost
tab stop and the
right
margin. Columns remain
vertically
aligned this
way.
A line
is
justified only
if itdoes notend with aretum, page,
or document character. Lines ending
with
these characters
and
containing
tabs are treated
like Left
Flush
text.
