OT: windowmaker's language button

[René Berber]

Hi,

This question is about WindowMaker not GNUstep but perhaps someone here knows 
the answer.

Anybody knows how to enable different languages on the "language button"?

Just for reference, the language button is an option that appeared in 
WindowMaker 0.8.2, you can enable it using Window Maker Preferences utility, in 
Miscellaneous Ergonomic Prefs, and it enables a button that shows the current 
keyboard language and can be used (in theory) to change languages.

TIA
