# How to write colon in the name of a node

I want to have have ":" in the name of one node but my compiler hanged when I put ":" there. I mean the following code in okay

\begin{tikzpicture}
\node[] at (5.1,-1) {$Z_t^{1 N}$};
\end{tikzpicture}


But the following one doesn't work

\begin{tikzpicture}
\node[] at (5.1,-1) {$Z_t^{1:N}$};
\end{tikzpicture}


Any idea?

• Colon or semicolon? I have no problem with the code, can you add a minimal example reproducing the issue? – egreg May 20 '16 at 23:19
• Both colon and semicolon work fine, if the snippet is expanded to a MWE (\documentclass{article}\usepackage{tikz}\begin{document}...\end{document}). – Heiko Oberdiek May 20 '16 at 23:21
• I don't know why it hangs whenever I run the code. – m0_as May 20 '16 at 23:29
• With the latest version of TeXLive, the MWE wrapper as suggested by @HeikoOberdiek works fine for me, too. – user2943160 May 20 '16 at 23:36
• Then something in your original code which you haven't shown here causes the problem. What that is we can't know. That's why you need to provide a complete example which reproduces the issue. – cfr May 21 '16 at 0:35
