NAME
filter-key, filter-keytrans - Generic key event translator
SYNOPSIS
filter-key: [<file>]
filter-keytrans: [<file>]
DESCRIPTION
This filter translates key events according to a set of translation
rules. This can be used to remap a keyboard.
OPTIONS
file The name of the configuration file. If none given, the filter
will first look for the file filter/keytrans in the user GGI
directory ($HOME/.ggi/ on UNIX), then in the base GGI directory
if not found.
CONFIGURATION
The mapping is specified through a simple text file, each line being a
translation rule. A line starting with a # is a comment. Each line must
contain 10 values in the following order:
modifier_mask
Consider only the bits set here.
modifier_value
The bits set above must match this value.
button_in, label_in, symbol_in
If this is not KEY_UNMAPPED==0xffff, the button/label/symbol of
the incoming key must match these fields.
modifier_changemask
Change these bits from the original modifiers...
modifier_ormask
... set them to these - one shouldn’t use that.
button_out, label_out, symbol_out
The data that is then sent by the keymapper. Any fields set to
KEY_UNMAPPED==0xffff will be copied from the incoming event.
EXAMPLE
Mapping a symbol:
# Take any key that produces a symbol of 0x41 (’A’) map it to ESC
#
# modmsk modval buttin lablin symin modchg modor butout labout symout
0x0000 0x0000 0xffff 0xffff 0x0041 0x0000 0x0000 0xffff 0xffff 0x001b
