Problem with apropos-documentation.

[Matt Hodges]

In GNU Emacs 21.3.50.3 (alphaev6-unknown-linux-gnu, X toolkit, Xaw3d scroll 
bars)
 of 2004-03-22 on tcdec3
Important settings:
  value of $LC_ALL: nil
  value of $LC_COLLATE: nil
  value of $LC_CTYPE: nil
  value of $LC_MESSAGES: nil

  value of $LC_NUMERIC: nil
  value of $LC_TIME: nil
  value of $LANG: nil
  locale-coding-system: nil
  default-enable-multibyte-characters: t

With a prefix argument, apropos-documentation gives an error:

I also find the documentation confusing:

    With optional prefix DO-ALL or if `apropos-do-all' is non-nil,
    also use documentation that is not stored in the documentation
    file and show key bindings.

Does this mean that I need to use a prefix argument to access
documentation of any library not distributed with Emacs? Also, when I
tried apropos-documentation with a prefix argument in Emacs 21.3, I
couldn't see any additional information about key bindings.

Thanks for any clarification on these issues.
