I have Ubuntu 13.10 and I would like to change the default searcher in Unity from "Computer and online sources" to "Applications" (Screenshots: http://imgur.com/a/Rc7Q3) I haven't been able to find any settings regarding the default, only filter results settings. I hope somebody can help!

You can directly summon the Aplication lens with Super+A
You can see other Unity desktop shorcuts if you keep Super pressed.
