Hello! I'd like to define a few more math environments and I have no idea how. I don't want too many. I use all kinds of extensions to AMS, and it has really useful environments, but I want one more, and I want to be able to select it in lyx.
Basically, it should be the same like the "lemma" environment. Only the name should be different. I want a data reduction environment. How can I create one? cheers, niko
