org: The very busy C-c C-c key

 
 15.7 The very busy C-c C-c key
 ==============================
 
 The key ‘C-c C-c’ has many purposes in Org, which are all mentioned
 scattered throughout this manual.  One specific function of this key is
 to add _tags_ to a headline (SeeTags).  In many other circumstances
 it means something like _“Hey Org, look here and update according to
 what you see here”_.  Here is a summary of what this means in different
 contexts.
 
    − If there are highlights in the buffer from the creation of a sparse
      tree, or from clock display, remove these highlights.
    − If the cursor is in one of the special ‘#+KEYWORD’ lines, this
      triggers scanning the buffer for these lines and updating the
      information.
    − If the cursor is inside a table, realign the table.  This command
      works even if the automatic table editor has been turned off.
    − If the cursor is on a ‘#+TBLFM’ line, re-apply the formulas to the
      entire table.
    − If the current buffer is a capture buffer, close the note and file
      it.  With a prefix argument, file it, without further interaction,
      to the default location.
    − If the cursor is on a ‘<<<target>>>’, update radio targets and
      corresponding links in this buffer.
    − If the cursor is in a property line or at the start or end of a
      property drawer, offer property commands.
    − If the cursor is at a footnote reference, go to the corresponding
      definition, and _vice versa_.
    − If the cursor is on a statistics cookie, update it.
    − If the cursor is in a plain list item with a checkbox, toggle the
      status of the checkbox.
    − If the cursor is on a numbered item in a plain list, renumber the
      ordered list.
    − If the cursor is on the ‘#+BEGIN’ line of a dynamic block, the
      block is updated.
    − If the cursor is at a timestamp, fix the day name in the timestamp.
