5.2.1 TODO keywords as workflow states

You can use TODO keywords to indicate different states in the process of working on an item, for example:

     (setq org-todo-keywords '("TODO" "FEEDBACK" "VERIFY" "DONE")
           org-todo-interpretation 'sequence)

Changing these variables only becomes effective in a new Emacs session. With this setup, the command C-c C-t will cycle an entry from TODO to FEEDBACK, then to VERIFY, and finally to DONE. You may also use a prefix argument to quickly select a specific state. For example C-3 C-c C-t will change the state immediately to VERIFY. If you define many keywords, you can use in-buffer completion (see Completion) to insert these words into the buffer. Changing a todo state can be logged with a timestamp, see Tracking TODO state changes for more information.
