This method is a wrapper function for the IOleCommandTarget::Exec method to enable scriptable execution of some command constants. IOleCommandTarget::Exec provides better performance and greater versatility than this method. You can obtain an IOleCommandTarget interface by calling QueryInterface on the IHTMLTxtRange interface using IID_IHTMLTxtRange for the IID.
