I'm trying to use Linux Libertine/Biolinum in combination with the menukeys package. Unfortunately, switching between the default font (everything scaled properly) and Libertine causes the predefined keys to shrink unproportionally compared to the text size. Any clues what's happening here?

Code:
\documentclass[10pt,a4paper]{scrartcl}
\usepackage{luatextra}
% toggle on / off
\setmainfont[Ligatures=TeX]{Linux Libertine O}
\setsansfont[Ligatures=TeX]{Linux Biolinum O}
%
\usepackage[os=mac]{menukeys}
\begin{document}
\keys{\cmd+\ctrl+A}
\end{document}

libertinepackage (it loads the OpenType fonts for you and provides a recent version of Libertine/Biolinum). – Silke Jan 29 '13 at 15:43libertinepackage. Now it works flawlessly. – bioslime Jan 29 '13 at 16:13
