Narrow to subtree and widen again - missing documentation

[Harri Kiiskinen <harri.kiiskinen@utu.fi>]

Hello all,

I just spent some time trying to find out, how to get back to the whole 
buffer after having narrowed in to a subtree ('org-narrow-to-subtree', 
C-x n s). I could not find any hints in the documentation as to how to 
return to the whole buffer. A search of the mailing list hinted, that 
the right word to use in this context might be "widen", and then I found 
the corresponding function 'widen' with the key C-x n w. This does not 
appear anywhere in the documentation (search through the one-page online 
html does not find the word "widen" at all), nor on the reference card, 
where a logical place for it would be after the narrow buffer -command 
in "Structure Editing".
	I realise that this is not an Org-function, but a part of the Emacs 
internals (I guess), but the documentation might still point to it.

But how do I clean the buffer after sparse tree by criteria -selection ( 
C-c / )?


Thanks for a wonderful productivity tool, though.
