Org mode supports insertion of empty structural elements (like
#+END_SRC pairs) with just a few key
strokes. This is achieved through a native template expansion mechanism.
Note that Emacs has several other template mechanisms which could be used in
a similar way, for example yasnippet.
To insert a structural element, type a ‘<’, followed by a template selector and <TAB>. Completion takes effect only when the above keystrokes are typed on a line by itself.
The following template selectors are currently supported.
For example, on an empty line, typing "<e" and then pressing TAB, will expand into a complete EXAMPLE template.
You can install additional templates by customizing the variable
org-structure-template-alist. See the docstring of the variable for
