Details:

There are a lot of user questions how to switch to menu when timeout is zero:

http://askubuntu.com/questions/87409/i-cant-get-grub-menu-to-show-up-during-boot

Ubuntu wiki for example have complicated scenario to get menu:

https://help.ubuntu.com/community/Grub2#Hidden

Main solution is to hold Shift (or Esc) button pressed after BIOS actions.

I search info grub for hold/shift/esc keywords - and doesn'r find anything
relevant.

Please add docs about such behavior!

[bug #40198] Document hold key for showing menu behavior when GRUB_TIMEOUT=0.

Follow-up Comment #1, bug #40198 (project grub):

Accoring to:

https://wiki.archlinux.org/index.php/GRUB#Hide_GRUB_unless_the_Shift_key_is_held_down

seems that holding shift  is customized by /etc/grub.d/xx-script:

if keystatus --shift; then
  set timeout=-1
