textmacros

The textmacros extension adds the ability to process some text-mode macros within \text{} and other macros that produce text-mode material. See the Differences from Actual TeX section for how text-mode is handled without this extension.

This extension is already loaded in all the components that include the TeX input jax, other than input/tex-base. To load the textmacros extension explicitly (when using input/tex-base for example), add '[tex]/textmacros' to the load array of the loader block of your MathJax configuration, and add 'textmacros' to the packages array of the tex block.

window.MathJax = {
  loader: {load: ['[tex]/textmacros']},
  tex: {packages: {'[+]': ['textmacros']}}
};

Alternatively, use \require{textmacros} in a TeX expression to load it dynamically from within the math on the page, if the require extension is loaded.

Since the textmacros extension is included in the combined components that contain the TeX input jax, it may already be in the package list. In that case, if you want to disable it, you can remove it:

window.MathJax = {
  tex: {packages: {'[-]': ['textmacros']}}
};

Available Macros:

The macros available in text mode with this extension are listed below. In addition, any macro that is defined via \def or \newcommand or in the macros section of the tex configuration block will also be processed if they only contain macros from the list below. Some extensions (e.g., the bboldx and textcomp packages) add more macros to this list when they are loaded.

Additional Packages

You can configure the textmacros extension to use additional packages, just as you can specify additional math TeX packages. Normally, these should be packages designed for text mode, but it is possible to load some of the regular TeX packages as text macros. For example

MathJax = {
  loader: {load: ['[tex]/textmacros', '[tex]/bbox']},
  tex: {
    packages: {'[+]': ['textmacros', 'bbox']},
    textmacros: {
      packages: {'[+]': ['bbox']}
    }
  }
}

would make the bbox extension available in text mode, so you could use \bbox inside \text{}, for example. Not all math-mode extensions are appropriate for textmode, but some can be usefully employed in text mode.
