Another interesting thing jamesh mentioned is that the notebook should
disable accelerators on non-visible pages. This kinda means that each
notebook page should have its own accelerator group.

One possible way could be to introduce an optional default_accel_group in
GtkWidget. Then gtk_widget_get_default_accel_group () propagates up the
widget hierarchy until it finds a widget with a defautl_accel_group. Some
widgets (like the notebook) could (possibly optionally) add default accel
groups automatically, and handle them (so that i.e. only the accel group
of the visible notebook page is active).

There is still the question of which widget the label is for, and what
action signal is to be invoked though, so this may not be such a good
idea.
