        Terminology change in execCommand command identifiers. Specifically, the name of
        "InsertNewline" command has been changed to "InsertLineBreak". This matches the
        terminology used by AppKit. It is also more accurate, since the insertion of a
        "br" element is what the command does. The inspiration for this change is so the
        -insertNewline AppKit method can be mapped to insert a new "div" element in
        a document and avoid ambiguity with what the javascript editing command does.
