The TeX input processor

The options below control the operation of the TeX input processor that is run when you include "input/TeX" in the jax array of your configuration. They are listed with their default values. To set any of these options, include a TeX section in your :meth:`MathJax.Hub.Config()` call. For example

MathJax.Hub.Config({
  TeX: {
    Macros: {
      RR: '{\\bf R}',
      bold: ['{\\bf #1}', 1]
    }
  }
});

would set the Macros configuration option to cause two new macros to be defined within the TeX input processor.

.. describe:: TagSide: "right"

    This specifies the side on which ``\tag{}`` macros will place the
    tags.  Set it to ``"left"`` to place the tags on the left-hand side.

.. describe:: TagIndent: ".8em"

    This is the amount of indentation (from the right or left) for the
    tags produced by the ``\tag{}`` macro.

.. describe:: MultLineWidth: "85%"

    The width to use for the `multline` environment that is part of
    the ``AMSmath`` extension.  This width gives room for tags at
    either side of the equation, but if you are displaying mathematics
    in a small area or a thin column of text, you might need to change
    the value to leave sufficient margin for tags.

.. describe:: Macros: {}

   This lists macros to define before the TeX input processor begins.
   These are name:value pairs where the `name` gives the name of the TeX
   macro to be defined, and `value` gives the replacement text for the
   macro.  The `value` canbe an array of the form `[value,n]`, where
   `value` is the replacement text and `n` is the number of parameters
   for the macro.  Note that since the `value` is a javascript string,
   backslashes in the replacement text must be doubled to prevent them
   from acting as javascript escape characters.

   For example,

   .. code-block:: javascript

       Macros: {
         RR: '{\\bf R}',
         bold: ['{\\bf #1}', 1]
       }

   would ask the TeX processor to define two new macros:  ``\RR``,
   which produces a bold-face "R", and ``\bold{...}``, which takes one
   parameter and set it in the bold-face font.
