The wskbd driver handles common tasks for keyboards within
framework. It is attached to the hardware specific keyboard
provides their connection to ``wsdisplay'' devices and a
The common keyboard support consists of:
+o Mapping from keycodes (defined by the specific keyboard
keysyms (hardware independent, defined in
+o Handling of ``compose'' sequences. Characters commonly
as separate keys on keyboards can be generated after either a special
``compose'' key is pressed or a ``dead accent'' character is used.
+o Certain translations, like turning an ``ALT'' modifier
+o Automatic key repetition (``typematic'').
+o Parameter handling for ``keyboard bells''.
+o Generation of ``keyboard events'' for use by X servers.
The wskbd driver provides a number of ioctl functions to
control key maps
and other parameters. These functions are accessible
through the associated
``wsdisplay'' device as well. A complete list is in
/usr/include/dev/wscons/wsconsio.h. The wsconsctl(8) utility allows access
to key maps and other variables.
The console locator in the configuration line refers to the
as input part of the operating system console. A device
containing a positive value here will only match if the device is in use
as system console. (The console device selection in early
is not influenced.) This way, the console device can be
connected to a
known wskbd device instance.
The wskbd driver traps certain key sequences intended to
functions. The Ctrl+Alt+Esc sequence will initiate the
ddb(4) kernel debugger
if the ``ddb.console'' sysctl(8) variable is set.
to a wsdisplay(4) device, Ctrl+Alt+Fx switches virtual terminals and the
Shift+PgUp and Shift+PgDn combinations provide scrollback
if the underlying hardware driver supports it.
