Note to self: how to get the tree back in Konqueror

When I close and re-open Konqueror, I lose the nifty tab on the left showing a list of directories as well as some quick links to common directories. Restoring it is a pain because it is not named logically.

The name is Navigation Panel, it is under the View menu, and the hotkey is F9.

Very handy when I can find it.
