# tikz usecase diagram send and receive shape

Im searching for a send and receive shape that has to look like this:

Is there some standard shape.misc to implement or even a manual to the shape.misc package?

• signal shape (from shapes.symbols) is what you want, combined with options signal to=east or signal from=west – JLDiaz Feb 7 '17 at 11:29
• Im not able to work that out. And i can't find any help online to this special symbols... Do you have some more information? – novski Feb 7 '17 at 12:44

Here is a MWE:

\documentclass[border=5pt]{standalone}
\usepackage{tikz}
\usetikzlibrary{shapes.symbols,positioning}

\begin{document}
\begin{tikzpicture}
\node[signal, draw, signal to=east, fill=cyan!20] (1) {Kellner rufen!};
\node[signal, draw, signal from=west, fill=cyan!20, below=of 1] (2) {Gast ruft Kellner};
\end{tikzpicture}
\end{document}


This is the result:

I think that shapes.symbols requires a recent version of PGF/TikZ. You can read more about it at page 709 of the latest PGF manual.
