well, that is pretty central. not all applications that use GTK are
office productivity/internet-presentation tools. the notion of focus
widgets and focus chains are actually impediments to some applications,
in which every key on the keyboard is potentially an accelerator. you
can even buy special keyboards or keyboard labels to work with such
applications. the fact that most apps don't work like this doesn't mean
that none should.

if you have NumLock on, that is treated as a modifier, and the key gets
tested as an accelerator before its passed to the focus chain.

not sure what a 2ndary XKB keyboard has to do with this ....
