The magic keys are a special compile time option available in 2.1.x or later
kernels.  They are quite powerful, and as such, have the ability to crash your
system. I know, as I needed to kill a runaway process and accidentally told it
to kill *all* processes, which it promptly did, including init!.  I'd misread
the the instructions and had pressed the wrong key, as there's another choice
that will kill everything *but* init.  I would use them sparingly, as a tool of
last resort.
