True - but the experience is better with F2 (on
"normal" computers/non-Chromebooks).
We've got a lot of feedback, and for most, people turn on their computers
and start tapping Escape when they want Grub. If it's mapped, this gets
intercepted by UiApp. Even if they exit, with BGRT in the equation, it
requires fairly precise timing to access Grub.
