I'm not 100% sure what the problem is but I have some suggestions.

When you recieve the key event, you should toggle the
GtkToggleButton with:

GTK_TOGGLE_BUTTON(tb)->active = !GTK_TOGGLE_BUTTON(tb)->active;
gtk_signal_emit_by_name(GTK_OBJECT(tb), "toggled");

This will change the toggle and emit the signal, which in turn
will cause the toggle button to call the "toggled" signal
callback you have set.
