The Browser normally displays the root directory (/.:)
  when it starts. Double click on the root directory to
  expand or open it. To collapse or close an expanded
  directory, double click on it.

  Directories, object entries, and soft links all have
  icons associated with them. Many object entries have
  unique icons based on their class. You can use the
  Filter menu to display only objects of a particular
  class.

  Customize your display format by choosing options
  listed on the View Menu.

  You can also specify a virtual root, a directory other
  than the root, at which you want to start displaying
  the namespace. You can then immediately focus on a
  particular directory. Use the Customize menu to specify
  a virtual root.
