mathjax-test

the following code ( using the "include mathjaxmacro:ket-example" - which inserts the mathjax ( LaTex) Command:
\newcommand{\ket}[1]{|#1\rangle}
Opens all the benefits of using LaTex-"Macros !!

 [[math label1]]
 [[include mathjaxmacro:ket-example]]
 \ket{x}
 [[/math]]

gives: 

 [[math label1]]
 \newcommand{\ket}[1]{|#1\rangle}
 \ket{x}
 [[/math]]

Which gives:

(1)

\begin{align} \newcommand{\ket}[1]{|#1\rangle} \ket{x} \end{align}
