Org Mode Markup Cheatsheet

Org Mode is a markup language, similar to Markdown, but more rich. Here's a cheat sheet.

Emacs: Org Mode Markup Cheatsheet

Have a look at the cheatsheet first.

The following shows you the commands to automatically insert the markup, and commands that navigate/manipulate the markup.

Create Headings

Heading starts with asterisk *, followed by a space.

* on the Musicality of Mathematics

** Abstract

Over the past thousand years, humanity has worked on on music and math.

** the Meaning of Musicality

One of the central problem is the definition of musicality.

** the Meaning of Math

The meaning of math is a ancient question. Here, we take a meta-physiology approach.

* on the Philosophy of Musicality

** Introduction

Of course, talk is cheap. But, is it, really? But before we can talk about it, we have to think about it. Does it imply thinking is cheaper?

Here we prove the fundamental theorem of musicality.

* the Absca Project

“I'm going to be lucky today, and my methodology is happy-go-lucky” —anonymous.

A wise man has said, but, we cut it directly by introducing the Absca project.

** Components of the Absca System


** Absca System and Logic

* the Relation of Absca, Musicality, and Math


Copy and paste the above in a file and save it as test.org.

Now, open the file. File ending in “.org” opens in org mode by default.

or Alt+x org-mode, to activate org mode in any buffer.

Show/Hide Sections

Create New Heading

Tree Branch Manipulation

Here are commands that move heading (and its content).

Open Files in org-mode Automatically

If you name your file ending in “.org”, emacs will open it in org-mode automatically.

You can also put this line as the first line of the file:

-*- mode: org -*-

Emacs will start org-mode when the file is opened.

If you want any file ending in “.txt” open in org-mode, add this line to your emacs init file:

(add-to-list 'auto-mode-alist '("\\.txt\\'" . org-mode))

Export to HTML

One great feature of org-mode is export to HTML.

Alt+x org-export-dispatchCtrl+c Ctrl+e】 → to show org export choices.

Ctrl+c Ctrl+e h h】 → export the file to HTML.

The newly generated file have the same name as your org file, but with “.html” extension, in the same directory.
