R help - Sep 2005 - tcltk - automatically moving cursor to last line of tktext box - how?

Hi; I have a program which writes lines to a tktext box (of height, say, 10)
with
      tkinsert(txto, "end", paste(so,"\n"))
I would like my program to be such that it automatically scrolls down through
the text box when it is full so that I always see the last 10 lines written. Can
anyone help on this?
Best regards
S??ren

How about 

tksee(txto, "end")

or maybe

tkyview(txto, "end - 10 lines")
