.Sh NAME
.Nm ukbd
.Nd USB keyboard support
.Sh SYNOPSIS
.Cd "ukbd*  at uhidev?"
.Cd "wskbd* at ukbd?"
.Cd "option UKBD_LAYOUT=XXX"
.Sh DESCRIPTION
The
.Nm
driver provides support for USB keyboards i.e. HID devices in the
.Dq keyboard
class.
Access to the keyboard is through the
.Xr wskbd 4
driver.
.Pp
The
.Nm
driver supports a number of different key mappings which
can be chosen from with the kernel option
.Dq UKBD_LAYOUT
at compile time or with the utility
.Xr wsconsctl 8
(variable:
.Dq keyboard.encoding )
at runtime.
Other mappings can be used if the whole keymap is replaced by means of
.Xr wsconsctl 8 .
The built-in mappings are at this time:
.Pp
.Bl -tag -width Ds -offset indent -compact

layout.
.El
.Pp
The KB_DE, KB_DK, KB_IS, KB_NO, KB_SF, KB_SG, KB_SV and KB_TR
mappings can be used in the KB_NODEAD
.Pq .nodead
variant.
This switches off the
.Dq dead accents .
.Pp
The KB_BE, KB_FR, KB_FR | KB_APPLE, KB_FR | KB_DVORAK, KB_JP, KB_UK, KB_US and
KB_US | KB_DVORAK
mappings can be modified
to swap the left Control and the Caps Lock keys by the
KB_SWAPCTRLCAPS variant bit or the
.Dq .swapctrlcaps
suffix.
.Pp
The KB_METAESC
.Pq .metaesc
option can be applied to any layout.
If set, keys pressed together
with the ALT modifier are prefixed by an ESC character.
(Standard behaviour is to add 128 to the ASCII value.)
.Sh EXAMPLES
To set a German keyboard layout without
.Dq dead accents
and sending an ESC character before the key symbol if the ALT
key is pressed simultaneously, use
.Ic wsconsctl keyboard.encoding=de.nodead.metaesc .
To set it at kernel build time, add the following
to the kernel configuration file:
.Bd -literal -offset indent
option UKBD_LAYOUT="(KB_DE|KB_NODEAD|KB_METAESC)"

.Xr usbhidctl 1 ,
.Xr intro 4 ,
.Xr uhidev 4 ,
.Xr usb 4 ,
.Xr wskbd 4 ,
.Xr wsconsctl 8
.Sh HISTORY
The
.Nm
driver
appeared in
.Nx 1.4 .
.Ox
support was added in
.Ox 2.8 .
.Sh BUGS
The
.Nm
driver is brought into action rather late in the boot process, so if
it is used as the console driver then
.Xr ddb 4
is not usable until late in the boot.
.Pp
The list of built-in mappings doesn't follow any logic.
It grew as people submitted what they needed.
