In particular, XKB extension is of interest. Layouts, utilities etc etc. Problems, bugs, complaining - whatever. XOrg, XFree, commercial X servers - whatever.
Xmodmap (classic X Window keyboard machinery) is a valid subject as well.
Feel free to discuss input methods, composing, keyboard PnP etc etc
Configuring the keyboards is a tough business sometimes - so it is a first priority topic here.
Hopefully here will be people here to discuss and comment, to ask and to answer. Everyone is welcome.
