[sugar] [PATCH] scroll activity list with the arrow keys

[Tomeu Vizoso]

Hi,

the patch below adds the Up and Down arrow keys to the
gtk.ScrolledWindow key bindings in the activity list as requested by
Eben.

But, if I understand correctly, this code alters the behavior of _all_
the gtk.ScrolledWindow instances in the shell. Two questions:

- To Eben: Is this desired?

- To anyone: Which place would be best for this code?

Thanks,

Tomeu
