+This is an Org mode document, using the ~.org~ extension (supported by GitHub).
+
+*Org mode* is an easy-to-write /plain text/ formatting syntax for authoring notes,
+articles, LaTeX documents, books, Web pages, Beamer slide decks and much more!
+
+This is a cheat sheet for *Org mode 8* (because of some markup syntax changes
+since Org mode 7), using [[https://github.com/fniessen/org-html-themes][ReadTheOrg CSS]].
+
+Reading through all the [[http://orgmode.org/org.pdf][documentation]] is highly recommended, but for the truly
+impatient, following are some quick steps to get started.

+** Document description
+
+#+begin_src org :eval never-export
+#+DESCRIPTION: This document catalogs a set of tips and tricks for composing documents in Org mode.
+#+KEYWORDS: org-mode, syntax, quick reference, cheat sheet, recommended practices, latex, beamer, html
+#+LANGUAGE: en
+#+end_src
+
+** Section numbering
+
+#+begin_src org :eval never-export
+#+OPTIONS: H:4
+#+end_src
+
+#+begin_src org :eval never-export
+#+OPTIONS: num:nil
+#+end_src
+
+** Table of contents
+
+Set the ~toc~ attribute to activate an auto-generated table of contents (limited
+to its 2 first levels) at the top of document.
+
+#+begin_src org :eval never-export
+#+OPTIONS: toc:2
+#+end_src
+
+#+begin_src org :eval never-export
+#+OPTIONS: p:t
+#+end_src
+
+#+begin_note
+The ~ALT_TITLE~ property allows to set an alternate title (shorter, for example)
+for a given headline in the table of contents and other running heads.
+#+end_note
+
+To locally insert the TOC at some random place, use the ~#+TOC: headlines [n]~
+feature; for example:
+
+#+begin_src org :eval never-export
+,#+TOC: headlines 2
+#+end_src
+
+** List of figures
+
+~#+TOC: figures~ is not implemented yet in the HTML backend.
+
+** List of tables
+
+~#+TOC: tables~ is already implemented in the HTML backend.
+
+** List of equations
+
+* Section titles (headings)
+
+#+begin_src org :eval no
+,* Biggest heading (level 1)
+
+New chapter.
+#+end_src
+
+#+begin_src org
+,** Bigger heading (level 2)
+
+New section.
+
+,*** Big heading (level 3)
+
+New sub-section.
+
+,**** Heading (level 4)
+
+New sub-sub-section.
+#+end_src
+
+** Numbered headings
+
+You can create numbered headings up to a certain level by setting an option:
+
+#+begin_src org
+,#+OPTIONS: H:4
+#+end_src
+
+* Paragraphs
+
+** Normal
+
+#+begin_src org
+A single newline has no effect.
+This line is part of the same paragraph.
+
+But an empty line
+
+demarcates paragraphs.
+#+end_src
+
+** Line breaks
+
+#+begin_src org
+By entering two consecutive backslashes, \\
+you can force a line break
+without starting a new paragraph.
+#+end_src
+
+** Horizontal rules
+
+#+begin_src org
+For an horizontal line, insert at least 5 dashes: this is some text above an
+horizontal rule
+-----
+and some text below it.
+#+end_src
+
+** Text width
+
+# Premiere Elements, page 111
+#
+# Vous pouvez créer ces objets en cliquant sur le bouton Nouvel| élément de le
+# fenêtre Média. (Le Chapitre 14 explique comment créer| des titres ; le
+# Chapitre 15 montre l'utilisation des barres et ton, de la| vidéo noir et de
+# l'amorce SMPTE.)

+# The principles of beautiful Web design, page 6
+#
+# In a figurative sense, the concept of visual balance is similar to that of
+# physical balance| illustrated by a seesaw. Just as physical objects have
+# weight, so do the elements of a layout.| If the elements on either side of a
+# layout are of equal weight, they balance one another.| There are two main forms
+# of visual balance: symmetrical and asymmetrical.
+
+One morning, when Gregor Samsa woke from troubled dreams, he found himself
+transformed in his bed into a horrible vermin. He lay on his armour-like back,
+and if he lifted his head a little he could see his brown belly, slightly domed
+and divided by arches into stiff sections. The bedding was hardly able to cover
+it and seemed ready to slide off any moment. His many legs, pitifully thin
+compared with the size of the rest of him, waved about helplessly as he looked.
+
+* Formatting text
+
+Text effects.
+
+** Bold and italic
+
+#+begin_src org
+/Emphasize/ (italics), *strongly* (bold), and */very strongly/* (bold italics).
+#+end_src
+
+Markup elements can be nested:
+
+#+begin_src org
+This is /italic text which contains _underlined text_ within it/, whereas _this is
+normal underlined text_.
+#+end_src
+
+Markup can span across multiple lines, by default *no more than 2*:
+
+#+begin_src org
+*This
+is not
+bold.*
+#+end_src
+
+Org mode does not interpret a marker surrounded by alphanumeric characters as an
+emphasis marker. So, you can't (easily) emphasize just part of a word:
+
+#+begin_src org
+Not feas*ible*.
+#+end_src
+
+** Monospace, superscript and subscript
+
+Other elements to use sparingly are:
+
+#+begin_src org
+- monospaced typewriter font for ~inline code~
+- monospaced typewriter font for =verbatim text=
+- +deleted text+ (vs. _inserted text_)
+- text with super^{script}, such as 2^{10}
+- text with sub_{script}, such as H_{2}O
+#+end_src
+
+** Smart punctuation
+
+If the XXX option is specified, Org mode will produce typographically correct
+output, converting straight quotes to curly quotes, ~---~ to em-dashes, ~--~ to
+en-dashes, and ~...~ to ellipses.
+
+* Lists
+
+Org markup allows you to create *bulleted* or *numbered* lists. It allows any
+combination of the two list types.
+
+** Unordered lists
+
+Itemized lists are marked with bullets. Create them with a minus or a plus sign.
+
+They are convenient to organize data, and make the document prettier, and easier
+to read.
+
+#+begin_src org
+- Item with some lengthy text wrapping hopefully across several lines. We add
+ a few words to really show the line wrapping.
+- Bullet.
+ + Bullet.
+ * Bullet.
+#+end_src
+
+** Checklists
+
+#+begin_src org
+- [X] Checked.
+- [-] Half-checked.
+- [ ] Not checked.
+- Normal list item.
+#+end_src
+
+** Ordered lists
+
+Enumerated lists are marked with numbers or letters:
+
+#+begin_src org
+1. Arabic (decimal) numbered list item. We add a few words to show the line
+ wrapping.
+ A. Upper case alpha (letter) numbered list item.
+ a. Lower alpha.
+ b. Lower alpha.
+ B. Upper alpha.
+2. Number.
+#+end_src
+
+You can have ordered lists with jumping numbers:
+
+#+begin_src org
+2. [@2] We start with point number 2.
+3. Automatically numbered item.
+#+end_src
+
+** Definition lists
+ :PROPERTIES:
+ :ID: f1a4a242-755b-4c38-9280-ee3f60e2b29a
+ :END:
+
+Labeled, multi-line lists.
+
+#+begin_src org
+- First term to define ::
+ Definition of the first term. We add a few words to show the line wrapping,
+ to see what happens when you have long lines.
+
+- Second term ::
+ Explication of the second term with *inline markup*.
+
+ In many paragraphs.
+#+end_src
+
+** Separating lists
+
+Adjacent lists sometimes like to fuse. To force the start of a new list, offset
+the two lists by an empty line comment:
+
+#+begin_src org
+- apples
+- oranges
+- bananas
+
+# Comment.
+
+- carrots
+- tomatoes
+- celery
+#+end_src
+
+* Tables
+
+Tables are one of the most refined areas of the Org mode syntax. They are very easy
+to create and to read.
+
+** Simple table
+
+#+begin_src org
+| Cell in column 1, row 1 | Cell in column 2, row 1 |
+| Cell in column 1, row 2 | Cell in column 2, row 2 |
+#+end_src
+
+Org tables have cells of at most one line long: there is no such thing as
+a multi-line table cell in Org.
+
+** Column formatting
+
+Columns are automatically aligned:
+
+- Number-rich columns to the right, and
+- String-rich columns to the left.
+
+*** Table with aligned cells
+
+If you want to override the automatic alignment, use ~<r>~, ~<c>~ or ~<l>~.
+
+#+begin_src org
+,#+CAPTION: Table with aligned columns
+| <r> | <c> | <l> |
+| 1 | 2 | 3 |
+| Right | Center | Left |
+| xxxxxxxxxxxx | xxxxxxxxxxxx | xxxxxxxxxxxx |
+#+end_src
+
+*** Table with column size adjusted
+
+** Header row
+
+You can create tables with an header row (by using an horizontal line of dashes
+to separate it from the rest of the table).
+
+#+begin_src org
+#+CAPTION: Table with an header row
+| Name of column 1 | Name of column 2 | Name of column 3 |
+|------------------+------------------+------------------|
+| Top left | Top middle | |
+| | | Right |
+| Bottom left | Bottom middle | |
+#+end_src
+
+** A very long table
+
+To test "sticky table headers"...
+
+| Name of column 1 | Name of column 2 | Name of column 3 |
+|------------------+------------------+------------------|
+| Top left | Top middle | |
+| 2 | | |
+| 3 | | |
+| 4 | | |
+| 5 | | |
+| 6 | | |
+| 7 | | |
+| 8 | | |
+| 9 | | |
+| 10 | | |
+| 11 | | |
+| 12 | | |
+| 13 | | |
+| 14 | | |
+| 15 | | Right |
+| 16 | | |
+| 17 | | |
+| 18 | | |
+| 19 | | |
+| 20 | | |
+| 21 | | |
+| 22 | | |
+| 23 | | |
+| 24 | | |
+| 25 | | |
+| 26 | | |
+| 27 | | |
+| 28 | | |
+| 29 | | |
+| Bottom left | Bottom middle | |
+
+** Table placement
+
+#+begin_src org
+#+ATTR_LATEX: :center nil
+| a | b |
+| 1 | 2 |
+#+end_src
+
+XXX Different from the following:
+
+#+begin_src org
+| a | b |
+| 1 | 2 |
+#+end_src
+
+** Align tables on the page
+
+*** Left
+
+Here is a table on the left side:
+
+#+begin_src org
+,#+LATEX: \noindent
+,#+ATTR_LATEX: :center nil
+| a | b | c |
+|---+---+---|
+| 1 | 2 | 3 |
+| 4 | 5 | 6 |
+,#+LATEX: \hfill
+#+end_src
+
+The ~noindent~ just gets rid of the indentation of the first line of a paragraph
+which in this case is the table. The ~hfill~ adds infinite stretch after the
+table, so it pushes the table to the left.
+
+*** Center
+
+Here is a centered table:
+
+#+begin_src org
+| a | b | c |
+|---+---+---|
+| 1 | 2 | 3 |
+| 4 | 5 | 6 |
+#+end_src
+
+*** Right
+
+And here's a table on the right side:
+
+#+begin_src org
+#+LATEX: \hfill
+#+ATTR_LATEX: :center nil
+| a | b | c |
+|---+---+---|
+| 1 | 2 | 3 |
+| 4 | 5 | 6 |
+#+end_src
+
+Here the ~hfill~ adds infinite stretch before the table, so it pushes the table
+to the right.
+
+** Table size
+
+#+begin_src org
+#+ATTR_HTML: :width 100%
+| Cell in column 1, row 1 | Cell in column 2, row 1 |
+| Cell in column 1, row 2 | Cell in column 2, row 2 |
+#+end_src
+
+** CSV
+
+You can fill a table from a CSV file using R commands.

+
+#+begin_src org
+,#+begin_quote
+Let us change our traditional attitude to the construction of programs:
+Instead of imagining that our main task is to instruct a computer what to do,
+let us concentrate rather on explaining to human beings what we want a
+computer to do.
+
+The practitioner of literate programming can be regarded as an essayist, whose
+main concern is with exposition and excellence of style. Such an author, with
+thesaurus in hand, chooses the names of variables carefully and explains what
+each variable means. He or she strives for a program that is comprehensible
+because its concepts have been introduced in an order that is best for human
+understanding, using a mixture of formal and informal methods that reinforce
+each other.

+
+#+begin_src org
+It's possible to add comments in the document.
+
+# This Org comment here won't be displayed.
+#+end_src
+
+#+begin_note
+Org doesn't support *comments inside paragraphs* since a comment ends
+a paragraph. However, you can mimic inline comments with export snippets, e.g.,
+~@@comment:...@@~.
+#+end_note
+
+#+begin_tip
+If you have tables (for example) that you want to ignore during export, one possibility
+is to use *comment blocks* or ~:noexport:~ subtrees. Another possibility is to
+*use* non-exported *drawers* (see #+OPTIONS: d:).
+#+end_tip
+
+If you want to ignore that part only during export, but still want to
+use keep it active in the buffer, I suggest to use a drawer, with an
+appropriate `org-export-with-drawers' value, e.g.,
+
+#+begin_src org

+#+end_src
+
+For PDF (LaTeX), one solution is to surround the code block such as:
+
+#+latex: \scriptsize
+#+begin_src R
+print("This block is in scriptsize")
+#+end_src
+#+latex: \normalsize
+
+** Line numbers
+
+Both in ~example~ and in ~src~ snippets, you can add a ~-n~ switch to the end of the
+~begin~ line to get the lines numbered:
+
+#+header: :eval no
+#+begin_src emacs-lisp -n
+(defun org-xor (a b)
+ "Exclusive or."
+#+end_src
+
+If you use a ~+n~ switch, the numbering from the previous numbered snippet will
+be continued in the current one:
+
+#+header: :eval no
+#+begin_src emacs-lisp +n
+ (if a (not b) b))
+#+end_src
+
+** Callouts
+
+In literal examples, Org will interpret strings like ~(ref:name)~ as labels, and
+use them as targets for special hyperlinks like ~[[(name)]]~ (i.e., the reference
+name enclosed in single parenthesis). In HTML, hovering the mouse over such
+a link will remote-highlight the corresponding code line, which is kind of
+cool.
+
+You can also add a ~-r~ switch which removes the labels from the source code.
+With the ~-n~ switch, links to these references will be labeled by the line
+numbers from the code listing, otherwise links will use the labels with no
+parentheses. Here is an example:
+
+#+header: :eval no
+#+begin_src emacs-lisp -n -r
+(save-excursion ; (ref:sc)
+ (goto-char (point-min))) ; (ref:jump)
+#+end_src
+
+In line [[(sc)]], we remember the current position. [[(jump)][Line (jump)]] jumps to
+~point-min~.
+
+* Math
+
+You can embed LaTeX math formatting in Org mode files.
+
+** Inline math expressions
+
+For *inline math* expressions, use the parentheses notation ~\(...\)~:
+
+#+begin_src org
+The formula \(a^2 + b^2 = c^2\) has been discovered by Pythagoras.
+
+Let \(a=\sin(x) + \cos(x)\). Then \(a^2 = 2\sin(x)\cos(x)\) because \(\sin^2x +
+\cos^2x = 1\).
+#+end_src
+
+#+begin_warning
+It's /not/ advised to use the ~$...$~ construct (both for Org and for MathJax).
+
+Don't forget that ~$~ is also a valid currency symbol!
+#+end_warning
+
+** Math expressions in display mode
+
+For mathematical expressions which you want to make *stand out, centered on their
+own lines*, use ~\[...\]~:
+
+#+begin_src org
+The /Euler theorem/:
+
+\[
+\int_0^\infty e^{-x^2} dx = {{\sqrt{\pi}} \over {2}}
+\]
+
+LaTeX allows to inline such ~\[...\]~ constructs (/quadratic formula/):
+\[ \frac{-b \pm \sqrt{b^2 - 4 a c}}{2a} \]
+#+end_src
+
+#+begin_warning
+Double dollar signs (~$$~) should not be used.
+#+end_warning
+
+#+begin_src org
+\[
+\left( \int_{0}^{\infty} \frac{\sin x}{\sqrt x}\,\mathrm{d}x \
+right)^{2} -
+\prod_{k=1}^{\infty} \frac{4k^{2}}{4k^{2}-1} +
+\frac{\lambda}{2n}\sum_{k=1} ^{n} \theta_{k} ^{2} x^{n} = 0
+\]
+#+end_src
+
+The equation may be wrong, but it's a nice one!
+
+** Equation numbers
+
+Differently from ~$...$~ and ~\(...\)~, an equation environment produces a *numbered*
+equation to which you can add a label and reference the equation by (label) name
+in other parts of the text. This is not possibly with unnumbered math
+environments (~$$~, ...).
+
+#+begin_src org
+The /Pythagoras theorem/:
+
+,#+name: pythag
+\begin{equation}
+a^2 + b^2 = c^2
+\end{equation}
+
+See equation [[pythag]].
+
+# The /sinus theorem/ can be written as the equation:
+#
+# \begin{equation}
+# \label{eqn:sinalpha}
+# \frac{\sin\alpha}{a}=\frac{\sin\beta}{b}
+# \end{equation}
+#
+# See equation [[eqn:sinalpha]].
+#+end_src
+
+Only captioned equations are numbered.
+
+Other alternatives: use
+- ~\begin{equation*}~ or
+- ~\begin{displaymath}~ (= the verbose form of the ~\[...\]~ construct).
+
+~M-q~ does not fill those.
+
+* Miscellaneous effects
+
+** Include Org files
+
+You can include another Org file and skip its title by using the ~:lines~ argument
+to ~#+INCLUDE~:
+
+#+begin_src org
+,#+INCLUDE: "chapter1.org" :lines "2-"
+#+end_src
+
+#+begin_note
+File inclusion, through INCLUDE keywords, is an *export-only feature*.
+#+end_note
+
+** Raw HTML
+
+# http://johnmacfarlane.net/pandoc/README.html
+
+You can include raw HTML in your Org documents and it will get kept as HTML
+when it's exported.
+
+#+HTML_BEGIN: <pre style="color:red">
+Text can be preformatted (in a fixed-width font).
+#+HTML_END: </pre>
+
+It is especially useful for more advanced stuff like images or tables where you
+need more control of the HTML options than Org mode actually gives you.
+
+Similarly, you can incorporate JS or do anything else you can do in a Web page
+(such as importing a CSS file).
+
+*** Native DIV blocks
+
+You can create named classes (to get style control from your CSS) with:
+
+#+begin_example
+,#+begin_myclass
+This text is wrapped in a myclass DIV...
+,#+end_myclass
+#+end_example
+
+You can also add interactive elements to the HTML such as interactive R plots.
+
+Finally, you can include an HTML file verbatim (during export) with:
+
+#+begin_src org
+,#+INCLUDE: "file.html" export html
+#+end_src
+
+Don't edit the exported HTML file!
+
+** Raw LaTeX
+
+You can also use raw LaTeX. XXX
+
+#+LaTeX_BEGIN: \begin{verbatim}
+Text can be preformatted (in a fixed-width font).
+#+LaTeX_END: \end{verbatim}
+
+* Footnotes
+
+#+begin_src org
+It is possible to define named footnotes[fn:myfootnote], or ones with automatic
+anchors[fn:2].
+#+end_src
+
+#+results:
+It is possible to define named footnotes[fn:myfootnote], or ones with automatic
+anchors[fn:2].
+
+* Useful extensions
+
+** Todo extension
+
+*** Dates
+
+Timestamps: [2014-01-16 Thu] and <2014-01-16 Thu>.
+
+*** TODO We need to achieve...
+
+*** DONE [#A] Buy GTD book :online:
+ :LOGBOOK:
+ - State "TODO" -> "DONE" [2014-01-16 Thu 09:52]
+ :END:
+
+By default, ~DONE~ actions will be collapsed.
+
+Note that I should probably implement that default behavior only for ~ARCHIVE~'d
+items.
+
+*** TODO [#A] Read GTD book
+ SCHEDULED: <2014-09-11 Thu>
+
+By default, *all* (active) entries will be expanded at page load, so that their
+contents is visible.
+
+That can be changed by adding such a line (into your Org document):
+
+#+begin_src org :eval no
+,#+HTML_HEAD: <script> var HS_STARTUP_FOLDED = true; </script>
+#+end_src
+
+*** TODO [#B] Apply GTD methodoloy
+ DEADLINE: <2014-12-01 Mon>
+ :PROPERTIES:
+ :HTML_CONTAINER_CLASS: hsCollapsed
+ :END:
+
+This section will be collapsed when loading the page because the entry has the
+value ~hsCollapsed~ for the property ~:HTML_CONTAINER_CLASS:~.
+
+Powerful, no?
+
+*** Some note :computer:write:
+
+You can add tags to any entry, and hightlight all entries having some specific
+tag by clicking on the buttons made accessible to you in the "Dashboard".
+
+*** Weekly review :computer:
+
+Now, you can even make your weekly review in the HTML export... Press the ~r~ key
+to start entering the "review mode" where all but one active entry are
+collapsed, so that you can really focus on one item at a time!
+
+** Bigblow extension
+
+The string ~fixme~ (in *upper case*) gets replaced by a "Fix Me!" image:
+
+#+begin_src org
+FIXME Delete this...
+#+end_src
+
+* Graphs with Graphviz

+
+The output from the *execution* of programs, scripts or commands can be inserted
+in the document itself, allowing you to work in the /reproducible research/
+mindset.
+
+To enable the Graphviz extension, we have to add it to the extensions list in
+the ~org-babel-load-languages~ variable.
+
+#+begin_src emacs-lisp :exports code
