How to Latex thread
 

Do we have a "How to Latex" thread specific to this forum (different forums can use slightly different versions of Latex)? I couldn't find one.

The particular question I had was how to make the symbol for the set of natural numbers (looks sort of like a capital N, but with an extra vertical line).

Does this help?

or to give a specific answer

\mathbb{CRQZNF}

should give
