The following code snippet might be helpful for you:

%tikz -width 0.5par

\usetikzlibrary{cd}

\begin{tikzcd}

  A \arrow[r, tail, two heads, dashed] & B

\end{tikzcd}

The first line (magic line) tune the default width of the generated image.

Hi there,

I’m trying to write some documents containing a lot of commutative diagrams, while the diagram created by tikz with default width looks large. I looked around to find some methods to define the default size or some function to modify the tree (like in-graphics? or get-graphical-object) and find nothing.

And possibly another question. How to unfold a specific `executable fold’? To keep the codes with diagrams, I have to press F10 many times to revert a former diagram to the code each time when I want to modify them. So is there any workaround?

Thanks!

Sincerely,
Hammer Hu
