Probably requested before, but I don't understand why ctr-alt-arrows work in the editor when I have project view focused: having the ability to navigate in it would greatly help, consider the following scenario:
-I have some node expanded in project view, and some code in the editor.
-From the editor I navigate to some package node in project view - packages are navigatable this way.
-When I see the class in package view I want to return back. Currently there is no easy way to do so.
