How can I jump to the selected object in the out-liner, I've got over 200 objects in my scene, all named cube.___ ... and I can't seem to find my selected object. How can I jump to it?
You can use Numpad . while hovering over the outliner, just like in the 3D view.
Another less ideal way is to under the drop down at the top, to select active.
The down side is that it will hide everything else
Another method I've been finding useful for dealing with the Outliner is to Duplicate the Area Window so it's actually another window. Now it can be sized up and moved to another screen. If you only use one screen, you can use Alt-tab to switch between the main Blender window and the Outliner window. (For OS X, it's CMD+TAB)
Now you can split the window multiple times and scroll each one so that you can see(hopefully) everything at the same time with just a glance.
