The commend was meant for Hans, all *you* have to do is update your TeX installation, afterwards you can try the following example: \useMPlibrary[mat] \setupmathstackers [both] [color=darkred, alternative=mp] \setupmathstackers [top] [color=darkred, alternative=mp] \setupmathstackers [bottom] [color=darkred, alternative=mp] \starttext $\overbracket {a+b+c+d} \quad \underbracket {a+b+c+d} \quad \doublebracket{a+b+c+d}$ \blank $\overparent {a+b+c+d} \quad \underparent {a+b+c+d} \quad \doubleparent {a+b+c+d}$ \blank $\overbrace {a+b+c+d} \quad \underbrace {a+b+c+d} \quad \doublebrace {a+b+c+d}$ \blank $\overbar {a+b+c+d} \quad \underbar {a+b+c+d} \quad \doublebar {a+b+c+d}$ \blank $\overleftarrow {a+b+c+d} \quad \overrightarrow {a+b+c+d} $ \blank $\underleftarrow {a+b+c+d} \quad \underrightarrow {a+b+c+d} $ \blank \stoptext Wolfgang
