Improve outliner Tray: Keyboard- navigation, renaming, etc

I use the Outliner quite a bit, often for (re)grouping and renaming groups and components. That takes a lot switching between mouse and keyboard.
So it would be nice, if it was possible to browse the tree by keyboard. up/down to move the focus, something to select, F2 to rename, … That’s what i miss, sure there’s more potential uses.
The layers tray already supports up/down to move the focus once a layer is clicked, but seemingly no other keyboard action. So this seems to be just a byproduct…
