Thanks, but  I realise that - not much of a saving IMO and more
cluttering up of name space. I guess I was asking if there is a "base
key map" shared by all "c like" file modes so I only have to define-key
once. No big deal I agree, but was just trying to tidy my emacs
libraries which are full of this & that at the moment as I built up my
emacs gdb support knowledge.
