RapidSpellDialog has all the features of a standard spell checker - allowing you to add words to the user dictionary, undo
the last operation, edit user options, change to the suggested word, change all matches to the suggested word, ignore a spelling
error, ignore all matches, smart suggestions and double word detection. RapidSpellDialog can check a selection of text, whole
documents, and allows manual alterations. The user can alter the main document while the dialog spell checking is in progress.
