This protocol declares the single action method ignoreSpelling:, which should be implemented by classes that need to work with Cocoa's Spelling panel. NSSpellChecker sends this message up the responder chain. Classes implement this method so that the Ignore button in the Spelling panel functions properly for the particular application or document implementation.
