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: .Pp .Cd "options ALTXBUTTONS" .Pp 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: .Pp .Cd options CAPS_IS_CONTROL .Pp 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: .Pp .Cd options FORCE_FUNCTION_KEYS .Pp On PowerBook models holding Option and up/down arrows change the screen brightness. .Sh SUPPORTED HARDWARE .Nx is known to support the following .Tn ADB keyboards: .Bl -bullet -offset indent .It On-board keyboards on PowerBook models .It Apple Standard Keyboard .It Apple Keyboard II .It Apple Extended Keyboard .It Apple Extended Keyboard II .It Apple Adjustable Keyboard .It Most third-party ADB keyboards are supported .El .Sh SEE ALSO .Xr adb 4 , .Xr wscons 4 , .Xr wskbd 4 , .Xr wsconsctl 8 .Sh BUGS The number pad on extended keyboards does not send out the proper key codes for many applications. .Pp The LEDs on extended keyboards are not functional under .Nx .
