OK. But question about realization is still open. All ideas are welcome

It's useful for loading some OS in special modes when it checks if you
press special key to enter special mode but it goes too fast and you
can't press it fast enough after pressing enter in GRUB.
Often it's failsafe modes. Sometimes I had this problem with windows
when it bugs and I can't enter in failsafe-mode because it goes too fast.
Another usage: chainloading boot-managers.
If you install other manager for special OS you can choose from GRUB
directly the configuration like: down down enter.
Not only boot-managers but also some OS like DOS including FreeDos if
multiple configurations are present in config file.
Ex: As I heard GRUB has problems loading FreeBSD. So you can install
FreeBSD native bootloader even have multiple BSD and/or configurations
and choose it from GRUB.
