.Nm akbd
.Nd Apple Desktop Bus keyboard driver for wscons
.Sh SYNOPSIS
.Cd "akbd* at obio?"
.Cd "wskbd* at akbd? console ?"
.Pp
.Cd "options ALTXBUTTONS"
.Cd "options CAPS_IS_CONTROL"
.Cd "options FORCE_FUNCTION_KEYS"
.
.Sh DESCRIPTION
.
This driver provides the
.Xr wscons 4
driver with support for Apple Desktop Bus keyboards.
.Bl -tag -width Cd
.
.It Cd "options ALTXBUTTONS"
.
To map
.Sm off
.Ao Option Ac \&+ Aq 1 ,
.Sm on
.Sm off
.Ao Option Ac \&+ Aq 2 ,
.Sm on
.Sm off
.Ao Option Ac \&+ Aq 3 ,
.Sm on
to mouse buttons 1, 2, and 3
respectively.
.
.It Cd options CAPS_IS_CONTROL
.
On macppc systems it is possible to tweak the keyboard driver to treat
the caps lock key on an
.Tn ADB
keyboard as a control key.
This requires special remapping because of
.Tn ADB Ap s
strange emulation of a mechanically-locked key.
.
.It Cd options FORCE_FUNCTION_KEYS
.
On macppc PowerBooks, several function keys double as
.Dq hot keys
.Pq brightness, volume, eject
when the
.Aq \&Fn
modifier is held down.
Mac OS\~X likes to reprogram the keyboard controller to send hot key
events when
.Aq \&Fn
is
.Em not
held down and send function key events when it is.
With this option you can transform the non-keyboard
.Dq button
events back into function key events.
.El
.
.Ss Special Keys
.
To work around the limited number of buttons found on most
.Tn ADB
mice, the following key sequences trigger mouse button events:
.Pp
.Bl -dash -compact
.It
.Sm off
.Ao Option Ac \&+ Aq LeftArrow
.Sm on
will work as the middle mouse button.
.It
.Sm off
.Ao Option Ac \&+ Aq RightArrow
.Sm on
will work as the right mouse button.
.El
.Pp
On PowerBook (mac68k) models the following key sequences are also
significant:
.Pp
.Bl -dash -compact
.It
.Sm off
.Ao Option Ac \&+ Aq UpArrow
.Sm on
increase screen brightness.
.It
.Sm off
.Ao Option Ac \&+ Aq DownArrow
.Sm on
decrease screen brightness.
.El
.
.Ss Supported Hardware
.
.Nx
is known to support the following
.Tn ADB
keyboards:
.Pp
.Bl -bullet -offset indent -compact
.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
.Tn ADB
keyboards are supported

.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 .
.Pp
In X11 with the default key mapping, middle and right mouse button events will
hold
.Ql Meta_L
and this will clobber the intended mouse button.
.Aq Option
should be remapped with
.Xr xmodmap 1
to the
.Aq Command
key:
.Bd -literal -offset indent
remove Mod4 = Super_L
remove Mod1 = Alt_L
add Mod1 = Super_L
