 % Manual shifts allow to customize dimensions on the base of user's needs: they should be introduced inside round braces as coordinate points. Coordinates, indeed, introduce more degree of freedom from the user's point of view while other solutions are more restrictive. Markers, therefore, are \emph{extensible}. Notice that is is not possible to use markers separately, but they should be declared in pair.
 %
+% From version 0.3 it is also possible to exploit a key-interface to set the \emph{shift-offsets}; for example, the previous example, could be done in another manner:
+% \begin{verbatim}
+% \begin{equation}
+% \tikzmarkin[below right offset={0.1,-0.4},above left offset={-0.1,0.5}]
+%  {right delim frac 2}
+% x+\dfrac{z}{y}=400

+% x+\dfrac{z}{y}=400
+% \tikzmarkend{right delim frac 2}
+% \end{equation}
+%
+% The list of keys available to customize the \emph{shift-offsets} are:
+% \begin{itemize}
+% \item \packoption{left}{-0.1/-0.075}: this key sets the left offset (the second value is active when the \smoption{fill} option is active);

+% \item \packoption{below}{-0.18}: this key sets the below offset;

+% \item \packoption{below right}{0.1/0.075,0.35}: this key sets contemporarely the below and the right offsets;
+%
+% \item \packoption{above left}{-0.1/-0.075,0.35}: this optikeyon sets contemporarely the above and the left offsets.
+%
+% \end{itemize}
+%
+% All the keys, not only those ones dedicated to the \emph{shift-offsets}, should be introduced in the first optional argument if \smoption{beamer} option is disables or in the second argument in the other case.

+% \tikzmarkend{marker 2}
+% \tikz[remember picture,overlay]\draw[use marker id=1,blue,xscale=-1](0,0)arc(270:90:1.5mm);
+% \tikz[remember picture,overlay]\draw[use marker id=2,blue](0,0)arc(270:90:1.5mm);

+% \[
+% \tikzmarkin[show markers,mark at=0,mark at=0.55]{marker 2}
+%  x+y=400
+% \tikzmarkend{marker 2}
+% \tikz[remember picture,overlay]\draw[use marker id=1,blue,xscale=-1](0,0)arc(270:90:1.5mm);
+% \tikz[remember picture,overlay]\draw[use marker id=2,blue](0,0)arc(270:90:1.5mm);
+% \]
+% \end{verbatim}
+%
+% The markers are visible when the \smkey{show markers} key is present, but for annotations it is preferable to not show them (by defaul they are not); moreover, markes can be customized: 
+% \begin{itemize}
