action

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

\mathtip{math}{tip}

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

\texttip{math}{tip}

Use tip (plain text) as tooltip for math.

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

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

Some examples are given below:

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

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 require extension is loaded.
