Hi all,
I'm quite ignorant in Lisp, but I find very convenient to bind the
expand to

ctrl shift "("

I've bound r-autoyas-expand with the following line in my .emacs

(define-key ess-mode-map [67108904] 'r-autoyas-expand )

Is there any simpler way to express 
ctrl shift "("
than the mysterious "67108904" number ?


I've found this number by
M-x global-set-key 
press the sequence
then
 C-x ESC ESC

to see the results 


It is described here

http://www.nongnu.org/emacs-tiny-tools/keybindings/

Unfortunately the "key-description", also described there,
do not work on my system.
