|
* 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.
