KBDMAP(5)		    BSD File Formats Manual		     KBDMAP(5)

NAME
     kbdmap — keyboard map file format for kbdcontrol

SYNOPSIS
     kbdmap

DESCRIPTION
     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 in
		   the range from 1 to 96.  Refer to the atkbd(4) manual page
		   for a list of predefined function keys.  You can use the -f
		   option of the kbdcontrol(1) utility to assign arbitrary
		   strings to function keys.

     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.

     lshifta|shifta
		   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
		   screen.

     panic	   Panic the system.  The sysctl(8) variable
		   machdep.enable_panic_key must be set to 1 to enable this
		   feature.

     paste	   Act as mouse buffer paste.

     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
     values.

     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.
