I understand these buttons in the Panasonic Let's > Note do NOTHING in firmware/hardware (i.e. if you don't hook something to > them, brightness is NOT changed)? no, they don't do anything in firmware/hardware.

However, this doesn't apply to the panasonic laptop hotkeys. They really don't do anything unless the os/driver takes care of it. --=20 - Harald Welte http://laforge.gnumonks.org/ =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D "Privacy in residential applications is a desirable marketing option."
