Finding the [MATH][/MATH] tags generator button in post menu??

Hi,

I cant seem to find the math button for the latex "wrappers" in the thread posting menu (the menu I am in right now as I type this). When I type [MATH[/tex] (I excluded the second bracket on purpose so the "MATH, /MATH" type would stay in the post, not being recognized by latex and subsuquently evaluated as nothing and thus appear as such) when I type that around some math equation as a test like this:

$\displaystyle x^n+y^n=z^n,\; n>2 $

Latex works just fine. But in the old forum their used to be a sigma symbol button which popped the latex tags right around what you were currently typing to make things much easier. Is the button still there and I'm just not seeing it? Or does it go by a different name now? Or is there some other simmilar short-cut to make the latex tags appear around your cursor?

Thanks for any help
