Using XP SP2 and I think earlier operating systems have the facility to copy and paste via a right mouse click, after highlighting all you have written, saves beggering around with keyboard buttons. For an on board spelling checker, Internet explorer has one available, as also Firefox, these spell check in the posting box as you type, by underlining in red, a miss spelled word. Hitting the back button should work to retrieve for copying to re-paste in a fresh posting box.
