ctrl-x does not work in grub-efi

Bug Description

Binary package hint: grub2

If I boot the Natty daily livecd in EFI mode and press e at the grub prompt to edit the command, it says to press ctrl-x to boot the entry. Pressing ctrl-x results in it just inserting the letter 'x' instead of booting.

Ctrl+x doesn't work in grub2 version, shipped with Ubuntu 11.04. As well as other ctrl+<...> hotkey doesn't work.

It won't insert "x" and other symbols like ctrl is not pressed, it just does nothing. Whereas alternative hot keys like F10 and others work well.

I am affected by this issue on Ubuntu 15.04 x86_64. I have AMI BIOS/UEFI. Ctrl-X does not work (but F10 works). In my case 'x' is inserted as if I did not press Ctrl key.
