org: Blocks

 
 2.9 Blocks
 ==========
 
 Org mode uses begin...end blocks for various purposes from including
 source code examples (SeeLiteral examples) to capturing time
 logging information (SeeClocking work time).  These blocks can be
 folded and unfolded by pressing TAB in the begin line.  You can also get
 all blocks folded at startup by configuring the option
 ‘org-hide-block-startup’ or on a per-file basis by using
 
      #+STARTUP: hideblocks
      #+STARTUP: nohideblocks
