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.
