Perhaps I wasn't clear the first time.  To interrupt the timer, you
press the <space> bar.  You can't edit anything until after that
point.

Yes, you can just edit the menu.lst with any text editor.
/boot/grub/menu.lst is a symlink to /boot/grub/grub.conf, same as
/etc/grub.conf.  You have to be root to edit it (them).

grub-install won't do what you want.
