So... SysRq was selected because you are not going to press
Alt-Printscreen-X by default.

I'm not sure if F10 is similar level of "impossible to press by
mistake", altrough holding up F10-B is likely not too common. Maybe it
should be some combination for chromebooks?
Leftshift-rightshift-F10-key? Ctrl-alt-del-key? :-).
