Hi,



I figured out what was wrong.



I’ve added (require ‘ess-site) to the beginning of my emacs file and it
works fine on my new computer now. So I think that means ESS hadn’t loaded
when I referenced ess-mode-map, and as there was nothing associated with
that Symbol I got the “"> Symbol's value as variable is void: ess-mode-map”
Error.



I’m still a little perplexed as to why my old computer didn’t need it
though. So if anyone has any ideas as to why I’d be interested in hearing
them (I know it works now so maybe I should just forget it, but I can’t
help but be a little curious as to exactly what was going on…..)



Thanks for everyone’s help

Thanks for the response Vincent,



My entire init file is below. It’s a bit of a hack of various peoples init
files including yours, plus some useful stuff I've picked up along the way.
(It’s a hack since I don’t really understand this language, but I’d really
like to try and understand it a bit better. I was wondering if anyone could
point me in the right direction of a good book / online resource / etc. Am
I correct in thinking it’s LISP?)



I keep getting the following error "> Symbol's value as variable is void:
ess-mode-map" for different 'handles'? (not sure if I'm using the correct
terminology there)



When I comment one out EMACS then finds another it doesn't like and I get a
similar error message for it



My entire init file is below and I've put in *red* *bold* each section I
get the above error message. The lines of code I’m having trouble with are:

*(define-key ess-mode-map [delete] 'delete-char)*

*(define-key inferior-ess-mode-map [delete] 'delete-char)*

*(define-key comint-mode-map [C-up]
'comint-previous-matching-input-from-input)*

*(define-key comint-mode-map [C-down]
'comint-next-matching-input-from-input)*

*(define-key ess-mode-map (kbd "C-d") 'comment-region)*

*(define-key ess-mode-map (kbd "C-S-d") 'uncomment-region)*
