Is rfkill new?

Does it monitor a hotkey to switch RF on and off?  Do you have one on
your keyboard?  And does pressing it make any difference?

My laptop has a slider switch, which occasionally doesn't seem to be
obeyed.  There's also a F key hotkey sequence, that rarely has seemed to
do anything.
