MACRO key, how to use it under X?

[Richard Klinda <ignotus@freemail.hu>]

Hoi All!

My 7-year-old keyboard has a unique key named "MACRO" on its lower left
corner.  `showkey' shows its keycode as 112, but under X I can't use this
key, even xev doesn't notice when I press/release it.

Any hints how can I use this button under X?
