keycodes 176  XF86AudioRaiseVolume  (top)
         174  XF86AudioLowerVolume  (bottom)
         144  XF86AudioPrev         (left)
         153  XF86AudioNext         (right)
         162  XF86AudioPlay         (middle)
work out of the box.

I had to set this one manually:
         158  XF86Sleep             (menu)
         (or use something appropriate like XF86Menu)
