I tried gtk_action_get_proxies() which works, but it looks like it
returns the menu item.  I'm still not sure how everything ties together.
 For example why is the function called gtk_action_get_proxies() it
seems to just return the menu item.  Anyway the way I got it to work,
which doesn't seem unreasonable, was to traverse the GtkWindow down
until I found the GtkExpander in that I was looking for and then I
emitted a signal.  I think this is what you were getting at.  So now my
callback for the action handler is a wrapper around
g_signal_emit_by_name(G_OBJECT(xpndr), "activate").  It finds the
expander and emits the signal.

Any idea how I can connect an accelerator to the Tab key?  In the
gtk_accelerator_name() function in the gtkaccelgroup.c file there isn't
a "<Tab>" in the list of accelerator name; however, I think there's a
way to add one, possibly with gtk_accel_group_connect(), but I'm not sure.
