5.2 Extended use of TODO keywords

The default implementation of TODO entries is just two states: TODO and DONE. You can, however, use the TODO feature for more complicated things by configuring the variables org-todo-keywords and org-todo-interpretation. Using special setup, you can even use TODO keywords in different ways in different org files.

Note that tags are another way to classify headlines in general and TODO items in particular (see Tags).

• Workflow states: From TODO to DONE in steps
• TODO types: I do this, Fred the rest
• Per file keywords: Different files, different requirements
