Snippet development Quickly finding snippets

There are some ways you can quickly find a snippet file:

  • M-x yas/new-snippet

    Prompts you for a snippet name, then tries to guess a suitable directory to store it, prompting you for creation if it does not exist. Finally, places you in a new buffer set to snippet-mode so you can write your snippet.
