I love this [Keyboard Maestro](http://www.keyboardmaestro.com/main/) macro for detecting @due(tomorrow) type strings when typing in [TaskPaper 3](http://www.taskpaper.com/) and automatically turning them into @due(2016-02-24) format. The scripting engine in TaskPaper 3 is completely reworked, so I'm still feeling my way around that, as well as continuing to be amazed at what Keyboard Maestro can do.
