% Similar to \cellpt command from drawstack package, but points
% to the next divider between cells. See drawstack.sty for the
% definition of \cellptr. This differs only in "\value{cellnb}-0.5"
% instead of "\value{cellnb}-1".
\newcommand{\cellptrdiv}[1]{
  \draw[<-,line width=0.7pt] (0,\value{cellnb}-0.5) +(2,\value{ptrnb}*0.1) -- +(2.5,\value{ptrnb}*0.45);
  \draw (2.5,\value{ptrnb}*0.5+\value{cellnb}-0.5) node[anchor=west] {#1};
