If you want QuarkXPress to check spelling as you type — especially in multiple languages — here’s your solution: AutoCorrectXT 3.5.
This $50 XTension for QuarkXPress 7/8/9 from AthenaSoft uses not only its own dictionaries, but it can also correct user-defined typing errors.
AutoCorrectXT fixes spelling errors in English, French, German, Dutch, Italian, Spanish, Portuguese, Russian, and Norwegian. (An Arabic version is available for $95.)
The newest version can automatically apply bullets and numbering to paragraphs, and adds a Greek dictionary.
