Comment 6 for bug 615029

Fixed, but we might still have to account for another problem.
From my commit message:
"""
After quick-adding a task, it gets selected in the treeview.
  The focus is passed to the treeview, so that the user can press "enter" to open
  the task.
  This could be annoying when adding several tasks, since the focus is stolen.
  Two solutions for that:
   - we avoid moving the focus
   - we add a keyboard shortcut for the quick add. Probably it's already there, I
   don't know.
