calling fluxbox menu (key binding needed)

[nico dreher <nico.dreher@hgkz.net>]

dear list,

I got fluxbox 0.1.14 installed on a powerbook g3.
I use bbconf (and bbkeys) to set some key bindings.
Since the powerbook's builtin-mouse-pad has only one key, I cannot call 
the fluxbox menu but with an external 2-wheel mouse (right-click).
(I have already tested all possible keys together with a mouse-click)

does anyone know who to define the key binding in bbconf to call the 
fluxbox-menu?
any other experiences/suggestions with that kind of problem?

thanks!
nico
