[NTG-context] about math accents \ddot

5 Nov 2009

      Dear all,

I am trying to put three dots over "X" in math mode.
In LaTeX, \dddot gives what I wanted by using amsmath packages.

In ConTeXt, $\ddot X$ gives two dots over X, but \dddot yields a  
"undefined control sequence" error.
"newmath" module doesn't support this accent.

Please give me a good way to do that.

Thank you.

Best regards,

Dalyoung
