Consider the following (inspired by this post):
\documentclass[border=10pt]{standalone}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\coordinate (a) at (0,0);
\coordinate (b) at (1,1);
\draw [->, red] (a) -| (b);
\draw [->] (a).. controls (a -| b) .. (b); % Shorter way to do this?
\end{tikzpicture}
\end{document}
it gives:
Is there a shorter way of obtaining the second type of path, more curved?
