AKBD(4)                    Kernel Interfaces Manual                    AKBD(4)

NAME
     akbd -- Apple Desktop Bus keyboard driver for wscons

SYNOPSIS
     akbd* at obio?
     wskbd* at akbd? console ?

     options ALTXBUTTONS
     options CAPS_IS_CONTROL
     options FORCE_FUNCTION_KEYS

DESCRIPTION
     This driver provides the wscons(4) driver with support for Apple Desktop
     Bus keyboards.

     To work around the limited number of buttons found on most ADB mice, one
     can map key sequences to trigger mouse button events.  To map Option+1,
     Option+2, Option+3 to mouse buttons 1, 2, and 3 respectively, add the
     following line to your kernel configuration file:

     options ALTXBUTTONS

     On macppc systems it is possible to tweak the keyboard driver to treat
     the caps lock key on an ADB keyboard as a control key.  This requires
     special remapping because of ADB's strange emulation of a mechanically-
     locked key.  To enable this code add the following line to your kernel
     configuration file:

     options CAPS_IS_CONTROL

     On macppc PowerBooks, several function keys double as "hot keys"
     (brightness, volume, eject) when the Fn modifier is held down.  Mac OS X
     likes to reprogram the keyboard controller to send hot key events when Fn
     is not held down and send function key events when it is.  To transform
     the non-keyboard "button" events back into function key events, place the
     following line in your kernel configuration file:

     options FORCE_FUNCTION_KEYS

SUPPORTED HARDWARE
     NetBSD is known to support the following ADB keyboards:

           o   On-board keyboards on PowerBook models

           o   Apple Standard Keyboard

           o   Apple Keyboard II

           o   Apple Extended Keyboard

           o   Apple Extended Keyboard II

           o   Apple Adjustable Keyboard

           o   Most third-party ADB keyboards are supported

     adb(4), wscons(4), wskbd(4), wsconsctl(8)

BUGS
     The number pad on extended keyboards does not send out the proper key
     codes for many applications.

     The LEDs on extended keyboards are not functional under NetBSD.
