It is well-known that the argument of certain commands (label, ref, cite are typical examples) almost never make any sense in LaTeX, and should be hence avoided when spell checking is performed.
I have found examples for environments where it is not working (TeXMaker), and instances where it seems to work (kile, TeXlipse).
However, I simply wasn't able to get any information about this problem in TeXnicCenter!
So the question is: is it somehow possible to perform spell checking in TeXnicCenter with the arguments of these commands ignored?

\begin{}and\end{}, for example, are still marked as a spelling error. Or self defined node names inTikZpictures. Or\label{}. But I think this can only be fixed by the author of the program in a new release. – Foo Bar Apr 14 '13 at 09:09\caption,\section,\title, etc. to be spell checked? – Mario S. E.
