KBDMAP(5) DragonFly File Formats Manual KBDMAP(5)
kbdmap -- keyboard map file format for kbdcontrol
A kbdmap file describes how the keys on a keyboard should behave. These
files can be loaded using kbdcontrol(1), or kbdmap(1) can be used to
select one of the default kbdmap files interactively. A kbdmap file can
be specified in rc.conf(5), to be loaded at boot time. The current
keymap may also be printed using kbdcontrol(1).
Each line in the file can describe a key or an accent. A `#' character
begins a comment, which extends to the end of the line.
The description of a key begins with the scancode for that key. Then the
effect of the key under combinations of shift, control and alt are listed
in the following order: no modifier, shift, control, control and shift,
alt, alt and shift, alt and control, alt and control and shift. The
action of the key under each modifier can be:
'symbol' The symbol the key should produce, in single quotes.
decnum The ASCII value to produce as a decimal number (see
ascii(7)). For example, 32 for space.
0xhexnum The ASCII value to produce as a hexadecimal number. For
example, 0x20 for space.
ctrlname One of the standard names for the ASCII control characters:
nul, soh, stx, etx, eot, enq, ack, bel, bs, ht, nl, vt, np,
cr, so, si, dle, dc1, dc2, dc3, dc4, nak, syn, etb, can,
em, sub, esc, fs, gs, rs, ns, us, sp, del.
accentname By giving one of the accent names, the next key pressed
will produce an accented character in accordance with that
accent. See the description of accents below. The accent
names are: dgra, dacu, dcir, dtil, dmac, dbre, ddot, duml,
ddia, dsla, drin, dced, dapo, ddac, dogo, dcar.
fkeyN Act as the Nth function key, where N is a decimal number.
lshift Act as left shift key.
rshift Act as right shift key.
clock Act as caps lock key.
nlock Act as num lock key.
slock Act as scroll lock key.
lalt|alt Act as left alt key.
btab Act as backwards tab.
lctrl|ctrl Act as left control key.
rctrl Act as right control key.
ralt Act as right alt (altgr) key.
alock Act as alt lock key.
ashift Act as alt shift key.
meta Act as meta key.
Act as left shift key / alt lock.
rshifta Act as right shift key / alt lock.
lctrla|ctrla Act as left ctrl key / alt lock.
rctrla Act as right ctrl key / alt lock.
lalta|alta Act as left alt key / alt lock.
ralta Act as right alt key / alt lock.
nscr Act as switch to next screen.
pscr Act as switch to previous screen.
scrN Switch to screen N, where N is a decimal number.
boot Reboot the machine.
halt Halt the machine.
pdwn Halt the machine and attempt to power it down.
debug Call the debugger.
susp Use APM to suspend power.
saver Activate screen saver by toggling between splash/text
panic Panic the system.
Finally, to complete the description of a key, a flag which describes the
effect of caps lock and num lock on that key is given. The flag can be
`C' to indicate that caps lock affects the key, `N' to indicate that num
lock affects the key, `B' to indicate that both caps lock and num lock
affects the key, or `O' to indicate that neither affects the key.
An accent key works by modifying the behavior of the next key pressed.
The description of an accent begins with one of the accent names given
above. This is followed by the symbol for the accent, given in single
quotes or as a decimal or hexadecimal ASCII value. This symbol will be
produced if the accent key is pressed and then the space key is pressed.
The description of the accent key continues with a list showing how it
modifies various symbols, by giving pairs made up of the normal symbol
and the modified symbol enclosed in parentheses. Both symbols in a pair
can be given in either single quotes or as decimal or hexadecimal ASCII
For example, consider the following extract from a kbdmap:
041 dgra 172 nop nop '|' '|' nop nop O
dgra '`' ( 'a' 224 ) ( 'A' 192 ) ( 'e' 232 ) ( 'E' 200 )
( 'i' 236 ) ( 'I' 204 ) ( 'o' 242 ) ( 'O' 210 )
( 'u' 249 ) ( 'U' 217 )
This extract configures the backtick key on a UK keyboard to act as a
grave accent key. Pressing backtick followed by space produces a back-
tick, and pressing a backtick followed by a vowel produces the ISO-8859-1
symbol for that vowel with a grave accent.
