When I have a source block (The "|" represents the point):

#+begin_src sh :eval no
chrome --remote-debugging-port
|

#+end_src

Then press =[C-c C-v d]=, it becomes like this:

#+begin_src sh :eval no
chrome --remote-debugging-port
#+end_src

#+begin_src
sh :eval no

#+end_src

       I try to make every word tell the meaning that I want to express.
