Dear List, I tried doing this...
I went to document in Layout menu, then I went to preamble and put this \newcommand\Z{\mathbb{Z}} And went to my document and changed to mathmode and typed \Z in it.. in LaTeX this would be understood as \mathbb{Z} and everything would go fine.. but in LyX, apparently the preamble was disregarded .. an error occured when I tried to view this in dvi saying that \Z is an undefined control sequence (which would have happened in LaTeX had I not but \newcommand in the preamble) .. So later I learned by reading the userguide that I have to use math-macro .. the documentation is however a bit confusing, should I type the following in the minibuffer math-macro Z \mathbb{Z} or what? I don't quite get this part of the documentation. And the definition box that appears after I define a macro.. it looks wierd in the document, I do hope it doesnt appear on the pdf/dvi/etc. output... I would suggest that the devoloper allow the \newcommand in the preamble to work rather than having a math-macro. Because that way it looks cleaner.
