Let's assume the Catalog is off. (he's not involve in this anyways)
(And the panel is off too)
Focus is on the tree. Press Tab to go to the list. Press tab again, you're not back in the tree! You need another tab to get there.
I dunno where he focus is, but it's quite annoying as I sometimes need to switch from tree to list back and forth....
