But I can't bind a keyboard shortcut to such a script which is exactly
what this thread is about... What I want to have in the end is my "VM
stop" shortcut, dynamically binding keys to monitor commands is just a
way to achieve this.

I really hate this "You don't need this, I know it better" attitude. If
it were only for the technical arguments, okay - I can understand that
you don't want to add another magic key, and yes, doing it dynamically
comes with some complexity. But all this talking about "non-existent
problems" makes me think that you don't... really care about what users
want if they are the wrong users (yes, I admit, this one is useful more
likely for developers and plain qemu users than for those running their
servers in KVM - but they are still users, right?)
