[NTG-context] Defined command troubles

5 Sep 2013

      Hi,

I just want to define a shortcut for framedtexts...

That's it:

\def\important{\dodoubleempty\doimportant}
\def\doimportant[#1][#2]{\bgroup
    \ifsecondargument
       \startframedtext[background=#2,frame=off,width=broad]%
       #1
    \else
       \startframedtext[background=screen,frame=off,width=broad]%
       #1
    \fi
    \stopframedtext
    \egroup}

It works perfectly with \important[Anything] but not with \important[Anything][red].

By the other hand, I want to define 'important' for use with start and end (startimportant ... \stopimportant) and not with single command. How can I get it?

Thanks,
Xan.
