NAME
     abtn - Apple brightness/volume/eject button control

SYNOPSIS
     abtn at adb?

DESCRIPTION
     The abtn driver allows you to dim the brightness of your display, change
     the volume of your speakers and eject the disc inserted into your drive.
     This driver only currently recognizes the dim, brightness, volume and
     eject buttons.  Numlock is also handled by this driver but it is silently
     ignored.

SEE ALSO
     adb(4), intro(4)

AUTHORS
     The abtn driver was written by Tsubai Masanari for NetBSD.
