Use the View menu to choose between formats for
  displaying the namespace or to choose a tree style.

  The Browser provides two basic formats for displaying
  the namespace: outline and tree. The outline format
  indents to show the hierarchy of entries in the
  namespace. Lines connect the entries with the tree
  format.

  If you select the Display Tree format, Tree Style
  is activated. You then have a variety of choices for
  customizing the appearance of the tree.

1  –  ch_display

  The Browser provides two basic formats for displaying
  the namespace: outline and tree. Outline format uses
  indenting to show the hierarchy of entries in the
  namespace. Lines connect the entries when the display
  is in tree format.

  To change the format, you can toggle between Display
  Tree or Display Outline from the View menu.

2  –  ch_treestyle

  The Browser offers a choice of three tree display
  styles. If you wish to change the tree style, pull down
  the Tree Style menu and select one of the following
  choices:

  -  Top - the root directory is centered at the top of
     the display and entries appear beneath it.

  -  Left - the root directory is centered at the left of
     the display and entries appear to the right of it.

  -  Outline - the root directory is at the top left of
     the display and the entries appear indented to the
     right of it.

  You may find changing the tree style helpful when you
  are viewing the organization of directories in your
  namespace.
