Window, Group, or Note Above Current Node

Tabs Outliner would be even more useful if there was a shortcut to create a window or group above the current node that included the current node in it. Of course, the "Note" node makes this easy, as it is only a few keystrokes away from organization, but the Window and Group nodes cause a bit of trouble with this because they always open a new tab. I may be glancing over something obvious (other than the fact that you can drag a note out of a larger window to create a separate one), but a shortcut to do something like this, or even switch between windows and boxes (assuming there is a difference) would be useful.
