Another interesting Emacs mode is Org-Mode. It permits to make annotations and manage to-do lists and projects using text files with some special marks.
The marks as interpreted by Emacs, so that it separates the various parts of the text, which facilitates obtaining information. It is possible to organize an agenda with appointments set up on specific dates and also tasks without due dates. With every agenda item, it is possible to associate tags, which can be used to filter search results. These features make Org-Mode a good resource for those who use GTD. For those who don’t know GTD, it is worth to take a look. It was proposed by David Allen and is described in the book “Getting things done”. A brief description of the method can be seen on this presentation which was given at Google and on this reference card.
