 Indentation in Formatted Text
 -----------------------------
 
    When editing formatted text, you can specify different amounts of
 indentation for the right or left margin of an entire paragraph or a
 part of a paragraph.  The margins you specify automatically affect the
 Emacs fill commands ( Filling) and line-breaking commands.
 
    The Indentation submenu provides a convenient interface for
 specifying these properties.  The submenu contains four items:
 
 `Indent More'
      Indent the region by 4 columns (`increase-left-margin').  In
      Enriched mode, this command is also available on `C-x <TAB>'; if
      you supply a numeric argument, that says how many columns to add
      to the margin (a negative argument reduces the number of columns).
 
 `Indent Less'
      Remove 4 columns of indentation from the region.
 
 `Indent Right More'
      Make the text narrower by indenting 4 columns at the right margin.
 
 `Indent Right Less'
      Remove 4 columns of indentation from the right margin.
 
    You can use these commands repeatedly to increase or decrease the
 indentation.
 
    The most common way to use these commands is to change the
 indentation of an entire paragraph.  However, that is not the only use.
 You can change the margins at any point; the new values take effect at
 the end of the line (for right margins) or the beginning of the next
 line (for left margins).
 
    This makes it possible to format paragraphs with "hanging indents",
 which means that the first line is indented less than subsequent lines.
 To set up a hanging indent, increase the indentation of the region
 starting after the first word of the paragraph and running until the end
 of the paragraph.
 
    Indenting the first line of a paragraph is easier.  Set the margin
 for the whole paragraph where you want it to be for the body of the
 paragraph, then indent the first line by inserting extra spaces or tabs.
 
    Sometimes, as a result of editing, the filling of a paragraph becomes
 messed up--parts of the paragraph may extend past the left or right
 margins.  When this happens, use `M-q' (`fill-paragraph') to refill the
 paragraph.
 
    The variable `standard-indent' specifies how many columns these
 commands should add to or subtract from the indentation.  The default
 value is 4.  The overall default right margin for Enriched mode is
 controlled by the variable `fill-column', as usual.
 
    The fill prefix, if any, works in addition to the specified paragraph
 indentation: `C-x .' does not include the specified indentation's
 whitespace in the new value for the fill prefix, and the fill commands
 look for the fill prefix after the indentation on each line.
