How to create sub-headers in org-mode (emacs)?

Question

Hello I was wondering how to create sub-headers in an org document. I have tried this:

* header 
  * sub-header
    Some text

The * works for the header part but will create bullets instead of sub-headers.

Answer 1

for these kind of questions the org-manual is the best place to check: https://orgmode.org/org.html#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

Hope, this helps!

Answer 2

As a supplement to the answer by @sanenr9, you can also enable a "clean view" that hides all but the last star in a heading if you prefer (see A Cleaner Outline View ): the asterisks are still there in the buffer but they are hidden using an overlay.

Another useful hint is to examine the "Org" entry in the menu: there are many useful commands there (generally with a keyboard shortcut as well). Eg you can add a new heading at the same level as the previous heading by clicking on the "New Heading" entry in the "Org" menu and you can then make it into a subheading by clicking on "Org/Edit Structure/Demote heading" menu item (or you can use the indicated keyboard shortcut M-<right> which is done by holding down the Meta key and pressing the right arrow key.)
