I've got a Western Electric 3666-1A key set (Autovon dial). I've tried
pressing the A, B, C and D keys while connected to both a Nortel DMS-200 (CO
Switch) and a Nortel Meridian-1 (PBX). In both cases I got reorder while
listening to dial tone (that is, no call had been established yet) and no
effect while an established call was in progress.

The Names of the additional keys are:
FO (Flash Override) adjacent to the 3 key
F (Flash) adjacent to the 6 key
I (Immeadiate) adjacent to the 9 key
P (Priority) adjacent to the # key (See note)

Note: My 3666-1A has a key designated as "A" where the # key is placed
on a normal dial pad. I don't know if this is standard for "Autovon"
dials. The tone generated by this key (according to a "digit
grabber") is that of a # key, however. Another interesting thing is
that the Star key (left of 0) is not an asterisk but rather it's a
real star! That is, a five pointed star, white lines on the gray
background (or is it a grey background?) with a hollow center.
