Because it was mentioned above: "Is there any reason why F10 under X Windows 
doesn't activate the visible toolbar ..."  I don't know who wrote that.

F10 activation of menus is actually Gnome/Gtk+ standard.  In fact, there is 
code in Emacs to turn it off for Gtk+-menus, because it interacts badly with 
tmm.  ALT activation is a bit trickier to do that just F10.
