Using vi(1) ":set sect" command I can verify that a section in my case is set to: sections="NHSHH HUnhsh" Why then on a *.tex file the above motion commands move to "{" in the first column? For example, in this file: 1 It is possible to show using linear algebra that Tresca cylinder has 2 a hexagon as a base, and von Mises condition has a circle. Because 3 neither is dependent on the volumetric stress, it is convenient to 4 plot stress states on 2D plane normal to $\sigma_{kk}=0$ plane, 5 {\em deviatoric plane}, see Fig. \ref{fig:plane} 6 7 \begin{figure}[htb] 8 \centerline{\includegraphics[width=6cm]{./figs/yield_plane.pdf}} 9 \caption{Tresca hexagon and von Mises circle on the deviatoric plane.} 10 \label{fig:plane} 11 \end{figure} 12 vi "[[" or "]]" move to line 5.
