‘GRUB_TIMEOUT_STYLE’

     If this option is set to ‘countdown’ or ‘hidden’, then, before displaying the menu, GRUB will wait
     for the timeout set by ‘GRUB_TIMEOUT’ to expire. If ESC is pressed during that time, it will display
     the menu and wait for input. If a hotkey associated with a menu entry is pressed, it will
     boot the associated menu entry immediately. If the timeout expires before either of these
     happens, it will boot the default entry. In the ‘countdown’ case, it will show a one-line
     indication of the remaining time.

Cheers,
David.
