 Justification in Formatted Text
 -------------------------------
 
    When editing formatted text, you can specify various styles of
 justification for a paragraph.  The style you specify automatically
 affects the Emacs fill commands.
 
    The Justification submenu provides a convenient interface for
 specifying the style.  The submenu contains five items:
 
 `Flush Left'
      This is the most common style of justification (at least for
      English).  Lines are aligned at the left margin but left uneven at
      the right.
 
 `Flush Right'
      This aligns each line with the right margin.  Spaces and tabs are
      added on the left, if necessary, to make lines line up on the
      right.
 
 `Full'
      This justifies the text, aligning both edges of each line.
      Justified text looks very nice in a printed book, where the spaces
      can all be adjusted equally, but it does not look as nice with a
      fixed-width font on the screen.  Perhaps a future version of Emacs
      will be able to adjust the width of spaces in a line to achieve
      elegant justification.
 
 `Center'
      This centers every line between the current margins.
 
 `None'
      This turns off filling entirely.  Each line will remain as you
      wrote it; the fill and auto-fill functions will have no effect on
      text which has this setting.  You can, however, still indent the
      left margin.  In unfilled regions, all newlines are treated as
      hard newlines ( Hard and Soft Newlines) .
 
    In Enriched mode, you can also specify justification from the
 keyboard using the `M-j' prefix character:
 
 `M-j l'
      Make the region left-filled (`set-justification-left').
 
 `M-j r'
      Make the region right-filled (`set-justification-right').
 
 `M-j f'
      Make the region fully-justified (`set-justification-full').
 
 `M-j c'
 `M-S'
      Make the region centered (`set-justification-center').
 
 `M-j u'
      Make the region unfilled (`set-justification-none').
 
    Justification styles apply to entire paragraphs.  All the
 justification-changing commands operate on the paragraph containing
 point, or, if the region is active, on all paragraphs which overlap the
 region.
 
    The default justification style is specified by the variable
 `default-justification'.  Its value should be one of the symbols
 `left', `right', `full', `center', or `none'.
