Cursor And Highlight; The Cursor And The Highlight - Canon Cat Reference Manual

The Cursor and the
Highlight
Tlte cursor is
the
blinking
object
on
the
screen.
It
usually
appears
to the
right of
a
solid, unblinking
rectangle
called
the
highlight.
The cursor and
the
highlightkeep track
ofyourplace
on
the
screen.
Like
a
pencil and
eraser,
each has a specialized
purpose
which
never changes.
What They Do
The cursor shows where the next character
you type
will
appear. The
highlight
shows
what
will
be erased
if
you
press
[ERASE].
This
is always true, so
we call
itthe
Fundamental
Cursor
Rule.
Changes
in
the
Cursor's
Appearance
The cursor
has
three distinct appearances:
narrow,wide,
and
extended. In addition
it
may
blink slowly
or
quickly.
Narrow Cursor
The cursor is
narrow when
the
cursor
and
the
highlight
both rest on the same
character,
and
both
are
blinking.
The
cursor
becomes
narrow
whenever
you
move it by leaping,
creeping, or scrolling.
When the cursor is narrow,
the
Fundamental
Cursor Rule
still applies: You
can
either type or
erase at
this
location.
Ifyou
type, the character
at the
cursor
will
be
pushed ahead
of
the
new characters.
If
you
erase,
the cursor
will
remove
the characters
to its
right.
The character
you
are on
will
disappear fi
rst.
