+/*************************************************************
+ *
+ *  MathJax/extensions/TeX/action.js
+ *  
+ *  Implements the \mathtip, \texttip, and \toggle macros, which give
+ *  access from TeX to the <maction> tag in the MathML that underlies
+ *  MathJax's internal format.
+ *  
+ *  Usage:
+ *  
+ *      \mathtip{math}{tip}        % use "tip" (in math mode) as tooltip for "math"
+ *      \texttip{math}{tip}        % use "tip" (in text mode) 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.
