Assembly: Microsoft.Office.Interop.Word (in microsoft.office.interop.word.dll)
The first character following a period is automatically capitalized when the CorrectSentenceCaps property is set to True. The FirstLetterExceptions collection includes exceptions to this behavior (for example, abbreviations such as "addr." and "apt.").
Use the FirstLetterExceptions property to return the FirstLetterExceptions collection.
Use the Add method to add an abbreviation to the list of first-letter exceptions.
Use FirstLetterExceptions(index), where index is the abbreviation or the index number, to return a single FirstLetterException object.
