I believe the problem here is not vi, but the way that characters are mapped
to the keyboard.  Holding down shift, control, and the "6" key does not
send a ctrl-^ character.  IMHO this is wrong, however 
I have spoken to the person at AT&T who does the kernel updates and he 
doesn't want to make a change here because the current keycodes for 
ctrl-shift-^ and ctrl-shift-_ are documented.  With the stock kernel, 
there is not even a way to generate the characters with ASCII values
0x1e or 0x1f from the keyboard.  The "fixdisk" currently
under development will be able to generate these codes from the keyboard
using a different key combination (such as ctrl-period). 
As an alternative, you can run the  keyfix.c program posted by Michael 
Ditto some time back.

Have you changed your "kill" character?  The default unix line kill 
character is @ and if you haven't changed it using "stty" vi will use
it for the same purpose.
