16.Sh DESCRIPTION
17The
18.Nm
19keyboard driver provides support for basic keyboard multiplexing.
20It is built around the idea of a
21.Dq "super keyboard" .
22The
23.Nm
24driver
25acts as a master keyboard consuming input from all slave keyboards attached to
26it.
27.Pp
28Slave keyboards can be attached to or detached from the
29.Nm
30keyboard driver with the
31.Xr kbdcontrol 1
32utility.

37.Xr ukbd 4
38.Sh CAVEATS
39The
40.Nm
41keyboard driver switches all slave keyboards into
42.Dv K_RAW
43mode.
44Thus all slave keyboards attached to the
45.Nm
46keyboard share the same state.
47The
48.Nm
49keyboard is logically equivalent to one keyboard with lots of duplicated keys.
50.Sh HISTORY
51The
52.Nm
53module was implemented in
54.Fx 6.0 .
