Not at all, as this feature would have to be in Mach. Maybe by giving the
terminal server some priviledge in Mach it could handle a hotkey itself.
Nothing of this is implemented, nor is it a critical feature.
This is the type of stuff you can easily do in a monolithical kernel.

It's not principally impossible, but harder to achieve and thus it is less
likely that someone will spend time on it.

A sub-hurd is not different from other user processes.
