Comment(by humitos):

 I was taking a look at this but it's not so easy.

 First of all I think that the !TreeView should not be able to get the
 focus[1] and we should call {{{HomeToolbar.__entry_activated_cb}}} if the
 key is not neither "Up" nor "Down"[2] but I didn't find how to get access
 to that function.

 [1] using {{{self.set_can_focus(False)}}} in {{{ActivitiesTreeView}}}
  * http://pygtk.org/docs/pygtk/class-gtkwidget.html#method-gtkwidget--set-
 can-focus
 [2] line 339 of {{{activitieslist.py}}}
