2.1 Headlines

Headlines define the structure of an outline tree. The headlines in Org start with one or more stars, on the left margin3. For example:

* Top level headline
** Second level
*** Third level
    some text
*** Third level
    more text
* Another top level headline

The name defined in org-footnote-section is reserved. Do not use it as a title for your own headings.

Some people find the many stars too noisy and would prefer an outline that has whitespace followed by a single star as headline starters. See Clean View.

An empty line after the end of a subtree is considered part of it and is hidden when the subtree is folded. However, if you leave at least two empty lines, one empty line remains visible after folding the subtree, in order to structure the collapsed view. See the variable org-cycle-separator-lines to modify this behavior.



See the variables org-special-ctrl-a/e, org-special-ctrl-k, and org-ctrl-k-protect-subtree to configure special behavior of C-a, C-e, and C-k in headlines. Note also that clocking only works with headings indented less than 30 stars.
