question about the \starteffect[hidden]

[Jeong Dal <haksan@me.com>]

Dear all,

I need to hide some part of the text while keep the space for them .
I found a very nice command “ \starteffct[hidden]”    
It works well in most cases.
But it couldn’t hide horizontal bars in math mode. Is there a way to hide horizontal bars also?

Here is an sample code.

Thank you.

\def\StartHide{\doifmode{nodetails}{\starteffect[hidden]}}   
\def\StopHide{\doifmode{nodetails}{\stopeffect}}   

\enablemode[nodetails]

\starttext

Here is the test file for hiding something.
Below, the same sentence is hiding.

But the horizontal bar in the fraction mode still appears.

	\frac{12}{1234567}
