 Outline Visibility Commands
 ---------------------------
 
    The other special commands of outline mode are used to make lines
 visible or invisible.  Their names all start with `hide' or `show'.
 Most of them fall into pairs of opposites.  They are not undoable;
 instead, you can undo right past them.  Making lines visible or
 invisible is simply not recorded by the undo mechanism.
 
 `C-c C-t'
      Make all body lines in the buffer invisible (`hide-body').
 
 `C-c C-a'
      Make all lines in the buffer visible (`show-all').
 
 `C-c C-d'
      Make everything under this heading invisible, not including this
      heading itself (`hide-subtree').
 
 `C-c C-s'
      Make everything under this heading visible, including body,
      subheadings, and their bodies (`show-subtree').
 
 `C-c C-l'
      Make the body of this heading line, and of all its subheadings,
      invisible (`hide-leaves').
 
 `C-c C-k'
      Make all subheadings of this heading line, at all levels, visible
      (`show-branches').
 
 `C-c C-i'
      Make immediate subheadings (one level down) of this heading line
      visible (`show-children').
 
 `C-c C-c'
      Make this heading line's body invisible (`hide-entry').
 
 `C-c C-e'
      Make this heading line's body visible (`show-entry').
 
 `C-c C-q'
      Hide everything except the top N levels of heading lines
      (`hide-sublevels').
 
 `C-c C-o'
      Hide everything except for the heading or body that point is in,
      plus the headings leading up from there to the top level of the
      outline (`hide-other').
 
    Two commands that are exact opposites are `C-c C-c' (`hide-entry')
 and `C-c C-e' (`show-entry').  They are used with point on a heading
 line, and apply only to the body lines of that heading.  Subheadings
 and their bodies are not affected.
 
    Two more powerful opposites are `C-c C-d' (`hide-subtree') and `C-c
 C-s' (`show-subtree').  Both expect to be used when point is on a
 heading line, and both apply to all the lines of that heading's
 "subtree": its body, all its subheadings, both direct and indirect, and
 all of their bodies.  In other words, the subtree contains everything
 following this heading line, up to and not including the next heading of
 the same or higher rank.
 
    Intermediate between a visible subtree and an invisible one is having
 all the subheadings visible but none of the body.  There are two
 commands for doing this, depending on whether you want to hide the
 bodies or make the subheadings visible.  They are `C-c C-l'
 (`hide-leaves') and `C-c C-k' (`show-branches').
 
    A little weaker than `show-branches' is `C-c C-i' (`show-children').
 It makes just the direct subheadings visible--those one level down.
 Deeper subheadings remain invisible, if they were invisible.
 
    Two commands have a blanket effect on the whole file.  `C-c C-t'
 (`hide-body') makes all body lines invisible, so that you see just the
 outline structure.  `C-c C-a' (`show-all') makes all lines visible.
 These commands can be thought of as a pair of opposites even though
 `C-c C-a' applies to more than just body lines.
 
    The command `C-c C-q' (`hide-sublevels') hides all but the top level
 headings.  With a numeric argument N, it hides everything except the
 top N levels of heading lines.
 
    The command `C-c C-o' (`hide-other') hides everything except the
 heading or body text that point is in, plus its parents (the headers
 leading up from there to top level in the outline).
 
    You can turn off the use of ellipses at the ends of visible lines by
 setting `selective-display-ellipses' to `nil'.  Then there is no
 visible indication of the presence of invisible lines.
 
    When incremental search finds text that is hidden by Outline mode,
 it makes that part of the buffer visible.  If you exit the search at
 that position, the text remains visible.
