Some commands There are pairedseveral places where you can search for command definitions: [[cmd:starttext|\starttext]] ... [[cmd:stopttext|\stoptext]] -->
== Arguments ==* [http://www.pragma-ade.com/general/qrcs/setup-en.pdf| setup-en.pdf] (and appropriate language variants) most up-to-date ConTeXt command reference (is this generated from [[source:cont-en.xml| cont-en.xml]]?)* [[manual:cont-eni.pdf|ConTeXt manual]]* [http://texshow.contextgarden.net/ texshow-web] on-line command reference (is this generated from [[source:cont-en.xml| cont-en.xml]]?)* [http://levana.de/emacs| etexshow] emacs browser for ConTeXt commands (is this generated from [http://texshow.contextgarden.net/ texshow-web]?) * xml description in [[source:cont-en.xml| cont-en.xml]] (and appropriate language variants) (typed manually or generated from sources?)

== Other notes ==
* In LaTeX optional arguments come before mandatory arguments. This is not true in ConTeXt. Optional argument can be at any position.
\definetextvariable
* If <code>key=value</code> pair is missing the value, than the key is assigned the default value.
<code>location=</code>
