Hi all,

is there function to extract all the code blocks in the selected region?

For example, can I select the region of the following two blocks and
extract them with just one command? Or I have to move cursor to each block
and extract them one by one?

   #+BEGIN_SRC sh :tangle foo.sh
     echo 'hello'
   #+END_SRC
   #+BEGIN_SRC python :tangle foo.py
     print 'hello'
   #+END_SRC

I doesn't find the extracting region command in manual. I would think this
can be a convenient feature to have?

Best,
Zhenjiang

Currently tangling does not support limiting to the active region.  It
shouldn't be too difficult to update org-babel-tangle to use
region-active-p to perform such limiting, unfortunately I personally
don't have the time to implement such an extension.

Best,
