Hello a45rpm33,
The short answer is "not really" or, more optimistically, "sort of."
There is no keyboard shortcut (such as CTRL+V for "paste") for creating a
new folder. However, you can use the following keys in sequence (meaning
don't hold down the ALT key while you press the other keys in order) to
create a new folder in Documents, Pictures, and Music:
ALT, F, W, F
This key sequence doesn't work in every location (the desktop, for example).
It seems to me that there ought to be a keyboard shortcut for creating a new
folder, so I'll make sure the right product team is aware of this request.
