This is a bit hacky, the alternative is you will probably need to modify the cursor position directly, that is, unless there is some existing public method on Edit ( which there might be but I didn't see in the myriad of 'Edit' methods ) <blockquote cite="mid:CAN7i3tkSHxzyS34AdNZtqNtU+X-a3qnUBsuhxMGeQ_do4qV3Lg@mail.gmail.com" type="cite"> <div class="moz-text-plain" wrap="true" graphical-quote="true" style="font-family: -moz-fixed; font-size: 12px;" lang="x-western"> <pre wrap=""> Thanks for reading my ramblings. ;) /Albert </pre> </div> </blockquote> thanks for taking the time with this nice addition Noel </body> </html>
