displaystylelyxmath-mode
Is there a way to achieve in LyX what one can achieve using \everymath{\displaystyle} in LaTeX, that is to force all inline math to look the same as math in equations (large integral signs, full-size numerator and denominator in fractions etc).
I have tried to add \everymath{\displaystyle} to preamble but it doesn't seem to help.
Update: Thank you, Torbjørn. I should have said that I actually want the change in LyX' WYSIWYG mode itself (if that's possible).
aligned is intended for this. But also align works if you use \parbox:
Text $\displaystyle\parbox{2cm}{\begin{align}
x &= 1 \\
y &= 0
\end{align}}$ \quad more text
\mathsf takes an argument, it doesn't make the following expression sans serif. You can switch to math sans serif, then get the underlying \mathgroup (\fam) number and then set that for the entire math expression:
\documentclass{article}
\begin{document}
\boldmath
\everymath{\mathsf{\xdef\mysf{\mathgroup\the\mathgroup\relax}}\mysf}
$abc$
\end{document}

I don't see anyone say it explicitly but it appears you know that you can add it to your LaTeX preamble in LyX. This won't change how the equations display in LyX while you're editing them i.e. when your cursor is in them. However, if you also turn on instant preview (in preferences under graphics) then it will change how they look the rest of the time.
