This section gives some sample uses for the hierarchical display and editing of plain text. • To-do lists often have subtasks, and so lend themselves to a hierarchical system. Org Mode facilitates this by allowing items to be
subdivided into simple steps (nested to-dos and/or
checklists), and given tags and properties such as priorities and deadlines. An
agenda for the items to be done this week or day can then be automatically generated from date tags. • Plain text
outlines. • Org files as interconnected pages of a
personal wiki, using the markup for links. • Tracking bugs in a project, by storing .org files in a
distributed revision control system such as
Git. • Extensive linking features, within the same file, to other files, to web pages, to emails, and also allows defining custom links. An org-mode document can also be exported to various formats (including
HTML,
LaTeX,
OpenDocument or plain text), these formats being used to render the structural outline in an appropriate fashion (including cross-references if needed). It can also use formatting markup (including LaTeX for mathematics), with facilities similar to those present in Markdown or LaTeX, thus offering an alternative to these tools. ==Org-babel==
