Sorry,maybe i cann't call it "hotbutton control"
I means that an application which can receive a
message from hardware button(like PALM Vx ) and send
a event to the nanowm,in this way the hardware button
can control the windows. (for example,You can control
the scrollbar of a window only with a hardware button
)

Thanks,I think this way is too difficult for me.
Currently I can only read "0" or "1" from the hardware
buttons,In your means,I must register my event to the
X-server?
