Hi Eli:

There is the [menu] button. It is unused at least in xterm because
it is not bound properly (I sent a message on yesterday).

By default [menu] is bound to the same than M-x, so it is a good trade
of to rebind it in the context-menu map, so by default the current
behavior is not affected. But also, because it will provide the same
behavior than other user interfaces around.

In other terminals (urxvt) such button sends S-<f6>, that is not bound
to anything either. And some others (gnome-terminal) intercept the
binding before reaching emacs... so, I think is a good trade off with
minimal impact.
