   I believe it is GRUB_HIDDEN_TIMEOUT in /etc/default/grub.

   Set it to 5. If no key is pressed during that timeout...then system
boots. I don't know whether the other timeout affects it. Actually on
my system the keyword is not even in the file...I got the info from
info -f grub -n "Simple Configuration"
