# Editor with a TeX-aware spellchecker

Is there around a TeX editor with a spellchecker that recognizes and handles properly TeX commands? For instance, I'd like it to underline with a red wavy line if I write "ntheorem" in my text, but not \usepackage{ntheorem}, figuring out automatically that the argument of usepackage is not meant to be a word but a "special command". Similarly, it should ignore most mathematical content (but not that inside $\text{}$).

You might also want to customize the ispell-tex-skip-alists variable. –  mbork Mar 12 '13 at 14:47
