Sublime Text 2 - Spell Check

Want to default spell checking on in say, LaTeX files, but not other languages?

1. Open a .tex document (to set the active syntax)
2. Go to Preferences → Settings - More → Syntax Specific - User.
3. Add this to the LaTeX.sublime-settings file that comes up (probably empty): {“spell_check”: true}
4. Save.
5. Reopen your .tex file.
