From /usr/include/linux/input.h
We maintain it here since it is such a painful mess.
Here is a little script to make it easier:
#!/usr/bin/perl
while (<>) {
$_ =~ s/-XK_/XK_/;
next unless /^XK_/;
chomp;
if (/^(\S+)(\s+)(\S+)/) {
$a = $1;
$t = $2;
$b = $3;
print "\tcase $a:${t}return $b;\n";
if ($a =~ /XK_[a-z]$/) {
$a = uc($a);
print "\tcase $a:${t}return $b;\n";
}
}
}
This only handles US kbd, we would need a kbd database in general...
Ugh: parse dumpkeys(1) or -fookeys /usr/share/keymaps/i386/qwerty/dk.kmap.gz
