Use the Check Spelling command in the Text menu to check the spelling in the current1 document. The Check Spelling command ignores HTML tags and attribute values.
By default, the spelling checker uses the U.S. English spelling dictionary. To change the dictionary, select Edit > Preferences > General (Windows) or Dreamweaver > Preferences > General (Macintosh), then in the Spelling Dictionary pop‑up menu select the dictionary you want to use. Dictionaries for additional languages can be downloaded from the Dreamweaver Support Center at www.adobe.com/go/dreamweaver_support.
