Thank you very much...
Yes, you cannot use "_" in a latex command name. Only lower and uppercase letters are allowed, unless you play with \catcode, which I do not recommend. The only non-letter character which is easy to use in command names is "@" because you can make it a letter through \makeatletter and then turn it again to its category through \makeatother. Note that LyX automatically encloses the latex preamble between \makeatletter and \makeatother, so you can safely use "@" there. -- Enrico
