Strange Keyboard Shortcut "Shift+*"

[qz33]

What exactly does Shift+* do in the tree panes of both xplorer2 and 2X Explorer?

At first it seems to explode a node but if you press it  a few more times it shows duplicates of the node but these are not really created because if you go back to the folder later there will be no change.

Just strange to me!

That's a known anomaly.
Pressing Shift+* in the tree pane on a node which already displays subfolders does nothing more than show a duplicate indented list of the subfolder names.  
Nothing is created except confusion.  :o
