      • TEXT_BOUNDARY_CHAR

        public static final int TEXT_BOUNDARY_CHAR
        Typically, a single character is returned. In some cases more than one character is returned, for example, when a document contains field data such as a field containing a date, time, or footnote reference. In this case the caret can move over several characters in one movement of the caret. Note that after the caret moves, the caret offset changes by the number of characters in the field, e.g. by 8 characters in the following date: 03/26/07.

        public static final int TEXT_BOUNDARY_LINE
        Range is from start of one line to the start of another line. This often means that an end-of-line character will appear at the end of the range. However in the case of some applications an end-of-line character indicates the end of a paragraph and the lines composing the paragraph, other than the last line, do not contain an end of line character.
