Protégé
...
Tree
...
Navigation
...
Using
...
Arrow
...
Keys
...
As
...
you
...
may
...
have
...
seen
...
while
...
opening
...
up
...
branches
...
in
...
Protégé,
...
the
...
hierarchy
...
window
...
gets
...
filled
...
up
...
quickly
...
and
...
it
...
makes
...
it
...
difficult
...
to
...
navigate
...
the
...
open
...
branch
...
and
...
move
...
from
...
branch
...
to
...
branch.
...
It
...
turns
...
out
...
the
...
arrow
...
keys
...
can
...
help.
...
If
...
you
...
click
...
on
...
a
...
class
...
name
...
you
...
can
...
use
...
the
...
up
...
and
...
down
...
arrow
...
keys
...
to
...
move
...
down
...
the
...
hierarchy
...
but
...
only
...
through
...
open
...
branches.
...
The
...
right
...
arrow
...
has
...
several
...
functions.
...
If
...
you
...
are
...
focused
...
on
...
a
...
class
...
with
...
children
...
it
...
will
...
open
...
up
...
the
...
branch.
...
The
...
next
...
use
...
of
...
the
...
right
...
arrow
...
will
...
move
...
the
...
focus
...
to
...
the
...
first
...
child;
...
otherwise
...
it
...
will
...
move
...
the
...
focus
...
down
...
the
...
hierarchy
...
to
...
sibling
...
classes
...
just
...
as
...
the
...
down
...
arrow
...
does.
...
The
...
left
...
arrow
...
can
...
do
...
two
...
things.
...
If
...
the
...
class
...
has
...
children
...
and
...
the
...
branch
...
is
...
open,
...
it
...
will
...
close
...
the
...
branch
...
or
...
it
...
will
...
allow
...
you
...
to
...
directly
...
navigate
...
to
...
the
...
parent
...
of
...
a
...
class
...
that
...
is
...
in
...
focus,
...
even
...
if
...
it
...
is
...
not
...
the
...
first
...
child
...
in
...
the
...
list.
...
The
...
arrow
...
keys
...
can
...
do
...
these
...
tasks
...
quickly,
...
you
...
just
...
need
...
to
...
be
...
sure
...
that
...
the
...
focus
...
is
...
in
...
the
...
hierarchy
...
window.
