Big braces and summations

So I know we can make big braces with

Code:

\begin{Bmatrix}

and the like, but how does one make them just for fitting larger sets--e.g.

Code:

\left(

does it for parentheses. Similarly, when I want to do a [code]\coprod[/tex] or [code]\sum[/code] or something similar, often I want to put two indexing sets, but that's not very well implemented (at least not in any of my limited experience). Usually I want one set listed under the other, e.g. a product over p prime and say p satisfying some congruence relation modulo k. Is there a way to do these things?

Ahh!!! So I don't do

Code:

\leftbrace

or

Code:

\biglbrace

but rather use the

Code:

\left

operator on the

Code:

\lbrace

Thanks Ilaggoodly!
