Hi Francis,

I often use `C-k' to kill the entire thread, but there are other ways
to mark and expire parts of a thread, or even the entire thread.

If you want to expire only the articles marked with the process mark,
you can use the `M-&' prefix.  Mark the articles first and then type
`M-& E' to expire all the process-marked articles.

A very useful key binding is also `T-#' which marks all the articles
of the current sub-thread with the process mark.  When combined with
the `M-& E' key binding, it provides a powerful command to expire only
parts of a large thread: `T-# M-& E'.

I'm not sure I understand what a sub-thread is in this context, so I'll
leave this one for someone with more Gnus and UI experience than me.

These are faces with various colors, and other font style options.  They
are commonly used as elements of the `gnus-cite-face-list'.  When quoted
material is displayed in an article buffer Gnus cycles through the list
of faces in `gnus-cite-face-list' as the nesting level of quotations

You can find out more about `gnus-cite-face-list' by reading its doc

    C-h v gnus-cite-face-list RET

and by looking it up in the index of the Gnus manual:

    C-h i m Gnus RET                    ; Fire up the Gnus manual
    i gnus-cite-face-list RET           ; Lookup variable in the Index.

The default behavior of Emacs is to wrap long lines.  What you wrote
above seems to be the result of a local customization.

If you have customized the `truncate-lines' and you want to _keep_
this sort of customization for everything else but to disable it for
Gnus, you may have to explicitly reset its value to nil in article

    (add-hook 'gnus-article-prepare-hook
      '(lambda ()
         (setq truncate-lines nil)))

FWIW, quickly toggling between truncated lines and wrapped lines is
something I often find useful, so I have the following in my ~/.emacs
file too:

    ;; Truncating of long lines is turned off by default, but I may
    ;; want to quickly toggle it back on with C-c t.
    (setq truncate-lines nil)
    (global-set-key "\C-ct" 'toggle-truncate-lines)

This way I can type `C-c t' to enter and leave truncate-lines mode.

Happy Gnus'ing :-)
