Another question: How to enable tab completion in grub-emu for variables/functions etc.?
It sounds like this completion works in "normal" grub. I am not aware of it. grub can complete commands, devices and files. Theoretically it can also complete command arguments if their definition was provided when command was registered. But I am not aware of any command that does it.
