KBDMAP 5 29.Os 30.Sh NAME 31.Nm kbdmap 32.Nd keyboard map file format for kbdcontrol 33.Sh SYNOPSIS 34.Nm 35.Sh DESCRIPTION 36A 37.Nm 38file describes how the keys on a keyboard should behave. 39These files can be loaded 40using 41.Xr kbdcontrol 1 , 42or 43.Xr kbdmap 1 44can be used to select one of the default 45.Nm 46files interactively. 47A 48.Nm 49file can be specified in 50.Xr rc.conf 5 , 51to be loaded 52at boot time. 53The current keymap may also be printed using 54.Xr kbdcontrol 1 . 55.Pp 56Each line in the file 57can describe a key or an accent. 58A 59.Ql # 60character begins a comment, 61which extends to the end of the line. 62.Pp 63The description of a key 64begins with the scancode for that key. 65Then the effect of the key 66under combinations of 67shift, 68control 69and alt 70are listed in the following order: 71no modifier, 72shift, 73control, 74control and shift, 75alt, 76alt and shift, 77alt and control, 78alt and control and shift. 79The action of the key 80under each modifier can be: 81.Bl -tag -width Ar 82.It ' Ns Ar symbol Ns No ' 83The symbol the key should produce, 84in single quotes. 85.It Ar decnum 86The 87.Tn ASCII 88value to produce 89as a decimal number 90(see 91.Xr ascii 7 ) . 92For example, 32 for space. 93.It 0x Ns Ar hexnum 94The 95.Tn ASCII 96value to produce 97as a hexadecimal number. 98For example, 0x20 for space. 99.It Ar ctrlname 100One of the standard names 101for the 102.Tn ASCII 103control characters: 104nul, 105soh, 106stx, 107etx, 108eot, 109enq, 110ack, 111bel, 112bs, 113ht, 114nl, 115vt, 116np, 117cr, 118so, 119si, 120dle, 121dc1, 122dc2, 123dc3, 124dc4, 125nak, 126syn, 127etb, 128can, 129em, 130sub, 131esc, 132fs, 133gs, 134rs, 135ns, 136us, 137sp, 138del. 139.It Ar accentname 140By giving one of the accent names, 141the next key pressed will produce 142an accented character 143in accordance with that accent. 144See the description of accents below. 145The accent names are: 146dgra, 147dacu, 148dcir, 149dtil, 150dmac, 151dbre, 152ddot, 153duml, 154ddia, 155dsla, 156drin, 157dced, 158dapo, 159ddac, 160dogo, 161dcar. 162.It fkey Ns Ar N 163Act as the 164.Ar N Ns No th 165function key, 166where 167.Ar N 168is a decimal number in the range from 1 to 96. 169Refer to the 170.Xr atkbd 4 171manual page for a list of predefined function keys. 172You can use the 173.Fl f 174option of the 175.Xr kbdcontrol 1 176utility to assign arbitrary strings to function keys. 177.It lshift 178Act as left shift key. 179.It rshift 180Act as right shift key. 181.It clock 182Act as caps lock key. 183.It nlock 184Act as num lock key. 185.It slock 186Act as scroll lock key. 187.It lalt|alt 188Act as left alt key. 189.It btab 190Act as backwards tab. 191.It lctrl|ctrl 192Act as left control key. 193.It rctrl 194Act as right control key. 195.It ralt 196Act as right alt (altgr) key. 197.It alock 198Act as alt lock key. 199.It ashift 200Act as alt shift key. 201.It meta 202Act as meta key. 203.It lshifta|shifta 204Act as left shift key / alt lock. 205.It rshifta 206Act as right shift key / alt lock. 207.It lctrla|ctrla 208Act as left ctrl key / alt lock. 209.It rctrla 210Act as right ctrl key / alt lock. 211.It lalta|alta 212Act as left alt key / alt lock. 213.It ralta 214Act as right alt key / alt lock. 215.It nscr 216Act as switch to next screen. 217.It pscr 218Act as switch to previous screen. 219.It scr Ns Ar N 220Switch to screen 221.Ar N , 222where 223.Ar N 224is a decimal number. 225.It boot 226Reboot the machine. 227.It halt 228Halt the machine. 229.It pdwn 230Halt the machine 231and attempt to power it down. 232.It debug 233Call the debugger. 234.It susp 235Use APM to suspend power. 236.It saver 237Activate screen saver 238by toggling between splash/text screen. 239.It panic 240Panic the system. 241The 242.Xr sysctl 8 243variable 244.Va machdep.enable_panic_key 245must be set to 1 to enable this feature. 246.It paste 247Act as mouse buffer paste. 248.El 249.Pp 250Finally, 251to complete the description of a key, 252a flag which describes 253the effect of caps lock and num lock 254on that key is given. 255The flag can be 256.Ql C 257to indicate that caps lock affects the key, 258.Ql N 259to indicate that num lock affects the key, 260.Ql B 261to indicate that both 262caps lock and num lock affects the key, 263or 264.Ql O 265to indicate that neither affects the key. 266.Pp 267An accent key works 268by modifying the behavior 269of the next key pressed. 270The description of an accent begins 271with one of the accent names 272given above. 273This is followed 274by the symbol for the accent, 275given in single quotes or 276as a decimal or hexadecimal 277.Tn ASCII 278value. 279This symbol will be produced 280if the accent key is pressed and 281then the space key is pressed. 282.Pp 283The description of the accent key 284continues with a list showing 285how it modifies various symbols, 286by giving pairs made up of the normal symbol and 287the modified symbol 288enclosed in parentheses. 289Both symbols in a pair can be given 290in either single quotes or 291as decimal or 292hexadecimal 293.Tn ASCII 294values. 295.Pp 296For example, 297consider the following extract from a 298.Nm : 299.Bd -literal -offset indent 300 041 dgra 172 nop nop '|' '|' nop nop O 301 dgra '`' ( 'a' 224 ) ( 'A' 192 ) ( 'e' 232 ) ( 'E' 200 ) 302 ( 'i' 236 ) ( 'I' 204 ) ( 'o' 242 ) ( 'O' 210 ) 303 ( 'u' 249 ) ( 'U' 217 ) 304.Ed 305This extract 306configures the backtick key on a UK keyboard 307to act as a grave accent key. 308Pressing backtick followed by space 309produces a backtick, and 310pressing a backtick followed by a vowel 311produces the ISO-8859-1 symbol 312for that vowel with a grave accent. 313.Sh FILES 314.Bl -tag -width
