org-mode capture template for code snippets
This code sets up three capture templates – for todos, media urls and code snippets (lines 4-7).
%? sets the exit point for the template, %^g prompts for a tag, %^{language} prompts for the language of the snippet and the remainder is boilerplate to create an org-mode entry (*) and an org-mode snippet (#+BEGIN_SRC\n\n#+END_SRC).
