Dear Erez, I probably was not clear enough. mhchem is a LaTeX package to write chemical compounds and reactions. \ce is a macro of mhchem, so you have call for mhchem in LyX under Document -> Settings -> Preamble. I would like to enter mhchem macros in math mode rather than in plain ERT, because then I have a preview. Somebody published in the LyX wiki a little HowTo and an example file mhchem.lyx: http://wiki.lyx.org/LyX/LyXForX (see the point Chemistry - Typesetting formulae) If you open mhchem.lyx with a plain text editor then that somebody managed to get this line into *mhchem.lyx*: \begin_inset Formula $\text{\ce{H+ + OH- <=>> H2O}}$ I can open mhchem.lyx with LyX and see a preview of the reaction. I can copy and paste it in LyX and see a preview. But I cannot reproduce typing this in with LyX 1.5.5 on Ubuntu 8.04 and I want to know if I miss something, if it is a bug or a regression (perhaps it did work only with older versions?). I hope I could point out my problem?! Yours sincerely Tobias Hilbricht > I think I don't really understand what equation you are trying to put > it. > \ce{...} is a macro of the mhchem package.
