It doesn't provide direct device 42driver entry points but makes its functions available via 43the internal 44.Xr wskbd 4 45interface. 46.Pp 47The 48.Nm 49driver supports a number of different key mappings which 50can be chosen from with the kernel option 51.Li PCKBD_LAYOUT 52at compile time or with the utility 53.Xr wsconsctl 8 54(variable: 55.Dq encoding ) 56at runtime. 57Other mappings can be used if the whole keymap is replaced by means of 58.Xr wsconsctl 8 . 59The builtin mappings are at this time: 60.Bl -column " KB_US|KB_COLEMAK" "wsconsctl" "language" 61.It Sy "option" Ta Sy "wsconsctl" Ta Sy "language" 62.It Li KB_US Ta us Ta English/US keyboard mapping (default) 63.It Li KB_DE Ta de Ta German with 64.Dq dead accents 65.It Li KB_FR Ta fr Ta French 66.It Li KB_DK Ta dk Ta Danish with 67.Dq dead accents 68.It Li KB_IT Ta it Ta Italian 69.It Li KB_UK Ta uk Ta British 70.It Li KB_JP Ta jp Ta Japanese 71.It Li KB_SV Ta sv Ta Swedish with 72.Dq dead accents 73.It Li "KB_US|KB_DECLK" Ta \&us.declk Ta English/US mapping for Tn DEC 74.It Ta Ta LK400-style keyboards with PC keyboard 75.It Ta Ta interface (e.g., LK461) 76.It Li "KB_US|KB_DVORAK" Ta us.dvorak Ta English/US keyboard with 77.It Ta Ta Do Dvorak Dc layout 78.It Li "KB_US|KB_COLEMAK" Ta us.colemak Ta English/US keyboard with 79.It Ta Ta Do Colemak Dc layout 80.It Li KB_NO Ta no Ta Norwegian with 81.Dq dead accents 82.It Li KB_PT Ta pt Ta Portuguese 83.It Li KB_ES Ta es Ta Spanish 84.El 85.Pp 86The 87.Li KB_DE , 88.Li KB_DK , 89.Li KB_NO 90and 91.Li KB_SV 92mappings can be used in the 93.Li KB_NODEAD ( 94.Dq .nodead ) 95variant. This switches off the 96.Dq dead accents . 97.Pp 98The 99.Li KB_US , 100.Li KB_JP 101and 102.Li KB_US|KB_DVORAK 103mappings can be modified 104to swap the left CTRL and the CAPS LOCK keys by the 105.Li KB_SWAPCTRLCAPS 106variant bit or the 107.Dq .swapctrlcaps 108suffix. 109.Pp 110The 111.Li KB_METAESC ( 112.Dq .metaesc ) 113option can be applied to any layout. If set, keys pressed together 114with the ALT modifier are prefixed by an ESC character. (Standard 115behaviour is to add 128 to the ASCII value.) 116.Pp 117Because PC keyboard hardware doesn't contain a beeper, requests for 118.Dq keyboard beeps 119cannot be handled directly. On alpha and i386 a helper device attached 120to the 121.Xr pcppi 4 122driver allows the use of the standard ISA speaker for this purpose. 123On acorn32, 124.Xr vidcaudio 4 125performs this function. 126.Sh EXAMPLES 127To set a German keyboard layout without 128.Dq dead accents 129and sending an ESC character before the key symbol if the ALT 130key is pressed simultaneously, use 131.Ic wsconsctl Fl w Ar encoding=de.nodead.metaesc . 132To set it at kernel build time, add 133.Cd options PCKBD_LAYOUT="(KB_DE | KB_NODEAD | KB_METAESC)" 134.br 135to the kernel configuration file. 136.Sh SEE ALSO 137.Xr isa 4 , 138.Xr pcppi 4 , 139.Xr wskbd 4 , 140.Xr wsconsctl 8 141.Sh BUGS 142The list of builtin mappings doesn't follow any logic. 143It grew as people submitted what they needed. 144
