filter-key, filter-keytrans : Generic key event translator

filter-key: [<file>]

filter-keytrans: [<file>]

This filter translates key events according to a set of translation rules. This can be used to remap a keyboard.

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.

The mapping is specified through a simple text file, each line being a translation rule. A line starting with a CW# 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 CWKEY_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

button_out, label_out, symbol_out

The data that is then sent by the keymapper. Any fields set to CWKEY_UNMAPPED==0xffff will be copied from the incoming event.

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
