.SH NAME

kbmap \- keyboard map
|
|
.SH SYNOPSIS
|
|
.nf
|
|
.B bind -a #κ /dev
|
|
|
|
.B /dev/kbmap
|
|
.fi
|
|
.SH DESCRIPTION
|
|
.PP
|
|
The
|
|
.I kbmap
|
|
device serves a one-level directory containing a single file,
|
|
.BR kbmap ,
|
|
representing the kernel's mapping of
|
|
keyboard scan codes to Unicode characters
|
|
(see
|
|
.IR cons (3)
|
|
and
|
|
.IR keyboard (6)).
|
|
.PP
|
|
Reads return the current contents of the map.
|
|
Each entry is one line containing three 11 character numeric fields, each followed by a space:
|
|
a table number, an index into the table (scan code), and the decimal value
|
|
of the corresponding Unicode character (0 if none).
|
|
The table numbers are platform dependent; they typically distinguish
|
|
between unshifted and shifted keys.
|
|
The scan code values are hardware dependent and can vary
|
|
from keyboard to keyboard.
|
|
.PP
|
|
Writes to the file change the map.
|
|
Lines written to the file must contain three space-separated fields,
|
|
representing the table number, scan code index, and Unicode character.
|
|
Values are taken to be decimal unless they start with
|
|
.B 0x
|
|
(hexadecimal) or
|
|
.B 0
|
|
(octal).
|
|
The Unicode character can also be represented as
|
|
.BI ' x
|
|
where
|
|
.I x
|
|
gives the UTF-8 representation of the character
|
|
(see
|
|
.IR utf (6)),
|
|
or as
|
|
.BI ^ X
|
|
to represent a control character.
|
|
.PP
|
|
The Unicode character can also be
|
|
.BI M n
|
|
to represent mouse button
|
|
.IR n .
|
|
The map
|
|
.B /sys/lib/kbmap/mouse-fn
|
|
maps the F1 through F5 keys to the three mouse buttons and the two
|
|
scroll wheel buttons.
|
|
Similarly,
|
|
.B mouse-csa
|
|
maps the left Control, Start, and Alt keys to the three mouse buttons.
|
|
These maps are useful on laptops without three-button mice.
