I have a lyx and a latex question First, is it possible to define new theorem environments in LyX? I looked through the help manuals, but could not find anything.
If not possible in LyX, of course I can use latex \newtheorem. Here the question is, is it possible to make this follow the style of an already defined theorem environment? Specifically, I want my environment to look like the theorem style in the IEEETran class, but if I just use \newtheorem it has a completely different style.
