action - Mathjax — ContextQMD

.. _tex-action:

action

The action extension gives you access to the MathML <maction> element. It defines three new non-standard macros:

.. describe:: \mathtip{math}{tip}

Use ``tip`` (in math mode) as tooltip for ``math``.

.. describe:: \texttip{math}{tip}

Use ``tip`` (plain text) as tooltip for ``math``.

.. describe:: \toggle{math1}{math2}...\endtoggle

Show ``math1``, and when clicked, show ``math2``, and so on.
When the last one is clicked, go back to ``math1``.

.. raw:: html

This extension is loaded automatically when the :ref:tex-autoload extension is used. To load the action extension explicitly, add '[tex]/action' to the :data:load array of the :data:loader block of your MathJax configuration, and add 'action' to the :data:packages array of the :data:tex block.

.. code-block:: javascript

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

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

.. _tex-action-commands:

action Commands

The action extension implements the following macros: \mathtip, \texttip, \toggle
