This is Emacs, you probably have your favorite template expansion, like [[https://elpa.gnu.org/packages/doc/tempel/tempel.html][TempEL]] or [[https://www.emacswiki.org/emacs/Yasnippet][Yasnippet]], as any system that can generate your text works fine.The magic isn’t hidden in markers, but shines plainly in the text itself.

** Editing src Blocks
I find editing prose in an Org file quite nice…editing code? Not so much. Many techniques you expect to use, like jumping to code definitions with the [[info:emacs#Looking Up Identifiers][Xref system]] or manipulating s-expressions in a Lisp with =paredit= or =smart-parens=, aren’t available.
With your cursor anywhere, the header line, anywhere in the body or one the =end_src= line, type ~C-c '~ to narrow to contents of that block with a mode based on the language on the header line.
Whew, now you can edit your code in a manner you expect. Type ~C-c '~ again to save and return to your full org buffer, or ~C-c C-k~ to cancel your changes.
Let’s add more [[info:org#Languages][languages]] to what is available, by running the following code:
#+begin_src emacs-lisp
(org-babel-do-load-languages
'org-babel-load-languages
'((emacs-lisp . t)
(python . t)))
#+end_src
Feel free to substitute the =python=, for your favorite language, or add more. Use =sh= for shell scripts, and =js= for Javascript. See [[https://orgmode.org/worg/org-contrib/babel/languages/index.html][Babel]] for details on languages that can be supported.
*Note:* If you don’t see you language’s pretty colors for its syntax, run this code (and put it in your init file):
#+begin_src emacs-lisp
(setq org-src-fontify-natively t)
#+end_src
