I use emacs org-mode and find feature of source code blocks extremely useful. However, If I want to say highlight a couple of lines in my source code block, is it possible to achieve? e.g.
#+BEGIN_SRC java int i = 0; m() //this is new call #+END_SRC
Here when I export my org-mode to HTML or some other format, I want
m() //this is new call
to stand out. The intention is convey your message as clearly as possible.
