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

On PowerBook models holding Option and up/down arrows change the screen brightness.
