org: Per-file keywords

 
 5.2.5 Setting up keywords for individual files
 ----------------------------------------------
 
 It can be very useful to use different aspects of the TODO mechanism in
 different files.  For file-local settings, you need to add special lines
 to the file which set the keywords and interpretation for that file
 only.  For example, to set one of the two examples discussed above, you
 need one of the following lines, starting in column zero anywhere in the
 file:
 
      #+TODO: TODO FEEDBACK VERIFY | DONE CANCELED
 (you may also write ‘#+SEQ_TODO’ to be explicit about the
 interpretation, but it means the same as ‘#+TODO’), or
      #+TYP_TODO: Fred Sara Lucy Mike | DONE
 
    A setup for using several sets in parallel would be:
 
      #+TODO: TODO | DONE
      #+TODO: REPORT BUG KNOWNCAUSE | FIXED
      #+TODO: | CANCELED
 
 To make sure you are using the correct keyword, type ‘#+’ into the
 buffer and then use ‘M-<TAB>’ completion.
 
    Remember that the keywords after the vertical bar (or the last
 keyword if no bar is there) must always mean that the item is DONE
 (although you may use a different word).  After changing one of these
 lines, use ‘C-c C-c’ with the cursor still in the line to make the
 changes known to Org mode(1).
 
    ---------- Footnotes ----------
 
    (1) Org mode parses these lines only when Org mode is activated after
 visiting a file.  ‘C-c C-c’ with the cursor in a line starting with ‘#+’
 is simply restarting Org mode for the current buffer.
