Oh, thanks. Is the "and" in the second screenshot typed with the \intertext command or are theire two seperate math mode environments? > I'm not sure why you would need to use \\[2em] in a math environment. > I show the use of it outside of the math environment. I know that. And i want to have the same possibility in the math mode. The \\[2em] was just an example (I need it some times ago in an array environment to correct the vertical spacing). I want to insert _arbitrary_ latex commands in the math mode. Otherwise I must type my equations in a latex-ERT box. Here is an other example. \documentclass[a4paper]{scrartcl} \usepackage{mathpazo} \usepackage[T1]{fontenc} \usepackage[utf8x]{inputenc} \usepackage{amsmath} \begin{document} This \begin{align*} f(z) & :=z^{2}\\ \intertext{with the substitution $z=\sqrt{x^2+y^2}$} & =x^2+y^2 \end{align*} is important. \end{document} How would you input the \intertext command with lyx? I started with "\intertext " "\{with " and now I am out of the brackets. An other problem is the local math mode in $z=...$. Thanks, Friedrich
