5.2.3 Multiple keyword sets in one file

Sometimes you may want to use different sets of TODO keywords in parallel. For example, you may want to have the basic TODO/DONE, but also a workflow for bug fixing, and a separate state indicating that an item has been canceled (so it is not DONE, but also does not require action). Your setup would then look like this:

     (setq org-todo-keywords
           '((sequence "TODO" "|" "DONE")
             (sequence "REPORT" "BUG" "KNOWNCAUSE" "|" "FIXED")
             (sequence "|" "CANCELED")))

The keywords should all be different, this helps Org mode to keep track of which subsequence should be used for a given entry. In this setup, C-c C-t only operates within a subsequence, so it switches from DONE to (nothing) to TODO, and from FIXED to (nothing) to REPORT. Therefore you need a mechanism to initially select the correct sequence. Besides the obvious ways like typing a keyword or using completion, you may also apply the following commands:

C-S-<right>

C-S-<left>

These keys jump from one TODO subset to the next. In the above example, C-S-<right> would jump from TODO or DONE to REPORT, and any of the words in the second row to CANCELED.

S-<right>

S-<left>

S-<<left>> and S-<<right>> and walk through all keywords from all sets, so for example S-<<right>> would switch from DONE to REPORT in the example above.
