Version 3 is now the current version of MathJax. This document is for version 2.

# Combined Configurations¶

MathJax comes with a number of pre-defined and pre-compiled configuration files
in the `MathJax/config`

directory. The `default.js`

file contains nearly
all the possible configuration options together with comments explaining them,
so you can use that file to customize MathJax to your needs. Simply load
it via

```
<script type="text/javascript" src="path-to-MathJax/MathJax.js?config=default"></script>
```

where `path-to-MathJax`

is the URL to the MathJax directory on your
server or hard disk. If you are using MathJax from a cdn, you can
view the contents of default.js as a
reference, but you will not be able to edit a cdn copy. It is
possible to use a cdn copy of MathJax with your own configuration
file, however; see Using a Local Configuration File with a cdn for details.

The remaining files in the `MathJax/config`

directory are
combined configuration files that include not just configuration
parameters but also the files that MathJax would need to load for
those configurations; you can browse the directory on Github. This
means MathJax will have to load fewer files, and since each file access requires
establishing connections over the network, it can be faster to load one larger
file than several smaller ones. See Loading and Configuring MathJax for more details about how to load configurations, and how
to modify the parameters for a configuration file.

The following sections describe the contents of the combined configuration
files. Each comes in two flavors: a standard version and a “full” version.
The standard version simply defines the output processor(s) that are part
of the configuration, but doesn’t load the code that implements the output
processor. The full version loads the complete output processors, so
everything that MathJax needs for the page should be loaded up front, and
there will be no delay once the page is ready to be processed. To obtain
the “full” version, add `-full`

to the end of the configuration file
name.

## The `TeX-MML-AM_CHTML`

configuration file¶

This configuration file is one of the most general of the pre-defined configurations. It loads all the main MathJax components, including the TeX, MathML, and AsciiMath preprocessors and input processors, the AMSmath, AMSsymbols, noErrors, and noUndefined TeX extensions, the CommonHTML output processor definitions, and the MathMenu and MathZoom extensions. It is equivalent to the following configuration:

```
MathJax.Hub.Config({
jax: ["input/TeX","input/MathML","input/AsciiMath","output/CommonHTML"],
extensions: ["tex2jax.js","mml2jax.js","asciimath2jax.js","MathMenu.js","MathZoom.js","AssistiveMML.js"],
TeX: {
extensions: ["AMSmath.js","AMSsymbols.js","noErrors.js","noUndefined.js"]
}
});
```

In addition, it loads the mml Element Jax, the TeX, MathML, and AsciiMath input jax main code (not just the definition files), as well as the toMathML extension, which is used by the Show Source option in the MathJax contextual menu. The -full version also loads the CommonHTML output jax main code, plus the CommonHTML mtable extension, which is normally loaded on demand.

See the tex2jax configuration section for
other configuration options for the `tex2jax`

preprocessor, and the
TeX input jax configuration section for options
that control the TeX input processor.

## The `Accessible`

configuration file [Deprecated]¶

This configuration file is essentially the same as
`TeX-AMS-MML_HTMLorMML`

except that it includes options that are
designed for assistive technology, particularly for those with visual
challenges.

Warning

*This file is deprecated* since the controls that make
MathJax work with screen readers are now available in the MathJax
contextual menu and the AssistiveMML extension, and so there is no need to set them in the
configuration file any longer. So you can use any of the other
pre-defined configurations and readers with special needs should be
able to change the MathJax settings themselves to be appropriate for
their software.

The Accessible configuration is equivalent to the following:

```
MathJax.Hub.Config({
config: ["MMLorHTML.js"],
jax: ["input/TeX","input/MathML","output/HTML-CSS","output/NativeMML", "output/PreviewHTML"],
extensions: ["tex2jax.js","mml2jax.js","MathMenu.js","MathZoom.js", "fast-preview.js", "AssistiveMML.js"],
TeX: {
extensions: ["AMSmath.js","AMSsymbols.js","noErrors.js","noUndefined.js"]
},
menuSettings: {
zoom: "Double-Click",
mpContext: true,
mpMouse: true
},
errorSettings: { message: ["[Math Error]"] }
});
```

This turns off the MathJax contextual menu for IE when MathPlayer is active, and passes mouse events on to MathPlayer to allow screen readers full access to MathPlayer. It also sets the zoom trigger to double-click, so that readers can see a larger version of the mathematics by double-clicking on any equation.

In addition, it loads the mml Element Jax, the TeX and MathML input jax
main code (not just the definition files), as well as the toMathML
extension, which is used by the Show Source option in the MathJax
contextual menu. The `-full`

version also loads the HTML-CSS, CommomHTML,
and NativeMML output jax main code, plus the HTML-CSS mtable extension, which
is normally loaded on demand.
