narrow and widen in org-mode

Just discovered org-narrow-to-subtree.

C-x n s     (org-narrow-to-subtree)

Narrow buffer to current subtree. 

C-x n b     (org-narrow-to-block)

Narrow buffer to current block. 

C-x n w     (widen)

Widen buffer to remove narrowing.

Narrowing is very handy when you want to export only subtree.
Note that contains active timestamp, link and a table presents itself great in Emacs, but copied to email turns into crap.
So you narrow to subtree that you want to send, than export as HTML, copy from your browser to email client and result might even look better than original.
