org: Initial visibility

 
 2.3.2 Initial visibility
 ------------------------
 
 When Emacs first visits an Org file, the global state is set to
 OVERVIEW, i.e., only the top level headlines are visible(1).  This can
 be configured through the variable ‘org-startup-folded’, or on a
 per-file basis by adding one of the following lines anywhere in the
 buffer:
 
      #+STARTUP: overview
      #+STARTUP: content
      #+STARTUP: showall
      #+STARTUP: showeverything
 
    The startup visibility options are ignored when the file is open for
 the first time during the agenda generation: if you want the agenda to
 honor the startup visibility, set ‘org-agenda-inhibit-startup’ to ‘nil’.
 
 Furthermore, any entries with a ‘VISIBILITY’ property (SeeProperties
 and Columns) will get their visibility adapted accordingly.  Allowed
 values for this property are ‘folded’, ‘children’, ‘content’, and ‘all’.
 
 ‘C-u C-u <TAB>’     (‘org-set-startup-visibility’)
      Switch back to the startup visibility of the buffer, i.e., whatever
      is requested by startup options and ‘VISIBILITY’ properties in
      individual entries.
 
    ---------- Footnotes ----------
 
    (1) When ‘org-agenda-inhibit-startup’ is non-‘nil’, Org will not
 honor the default visibility state when first opening a file for the
 agenda (SeeSpeeding up your agendas).
