UNDO
and Highlighting
[UNDO]
leaves
the
text and
cursor
as
they were before
you
extended the highlight.
Automatic Highlighting
Some
commands
-
[COPY], [SEND],
[BOLD], [CAPS],
and
[UNDERLINE]
-
allow you to skip the step
of pressing both
LEAP
keys
in order to extend
the
highlight. Simply using
the command after a
leap
(or
after
typing
as described
above
in
Highlighting Recently Typed Text,
page
20)
causes
the highlight
to
extend and
the
command
to
be
carried
out.
Unhighlighting
If
the
highlight is
extended and
you press and
release
[LEAP->I, the
highlight collapses to the size
ofone charac-
ter,
resting on the last character of the
formerly
highlighted
text.
This
is
called unhighlighting
forward, since
the
highlight
collapses
to its forward end.
The cursor does not change
position when you
unhighlight
forward.
It
remains
one character
to
the
right
of
the
highlight.
Thus
the
cursor is left wrde
after
unhighlighting
forward (se,eWide
Cursor, page 3).
If
the
highlight
is extended
and
you press and
release
[<-LEAP], the
highlight collapses to the size
ofone charac-
ter, resting on the
first
character
of
the formerly high-
lighted
text. At
the same
time,
the
cursor leaps
backward
and lands
on the
same
character.
This
is
called
unhigh'
lighting bachuard. Unhighlighting backward changes the
cursor
from wide
to
narrow (seeNarrow Cursor,page2).
UNDO
and Unhighlighting
Using
[UNDO]
restores the
highlight
to
the
way
it
was
before you
unhighlighted. In
other
words,
it
rehighlights
the
text.
Rehighlighting
After unhighlighting, you
can
rehighlight, or
bring
back
the
extended
highlight, by pressing both
LEAP keys again.
The Cat rememben
the
area
you highlighted
until
you
begin
typing or leap after unhighlighting.
