Yes, i see that now.  When i type:

cat > test.txt

Then hit the arrow key it gives me control+[[B, thats why i suggested that
and not escape+[B.  And i pulled \e[[B from my memory of your previous
e-mail, not from the e-mail itself.  So my apologies.

As for running mutt through expect, it seems to ignore everything i send,
even if I just try and open it up quit.  So I dont think there is actually
anything wrong with what your sending, just how its being interpreted by
mutt.
