+\begin{key}{/tikz/commutative diagrams/center shift=\meta{dimension} (initially 0.575ex)}
+\end{key}
+
+The picture below shows some of the available anchors. All anchors
+provided by \texttt{rectangle} are available and behave exactly the
+same, except for \texttt{center}, \texttt{west}, \texttt{east}, and
+the numerical anchors. The anchors \texttt{real center}, \texttt{real

+ \end{tikzpicture}
+\end{center}
+
+This shape is used in the matrix cells inside the \texttt{tikzcd}
+environment to ensure arrows between nodes in the same row are drawn
+horizontally. Roughly speaking, when \tikzname{} draws a path between
+two nodes, it chooses endpoints lying on their borders in such a way
+that the path points towards the \texttt{center} of those nodes. With
+the \texttt{rectangle} shape, the anchor \texttt{center} lies halfway
+between two nonadjacent vertices and therefore its position depends on
+the height and depth of the text.
