title: keymap to replace letter in Sublime text 3
body: <p>I am trying to make a keymap to replace some letter combination to fix certain special latin characters Example: </p>
  
  <p>I am trying to make a Spanish "ñ" with "gn":</p>
  
  <pre class="lang-js prettyprint-override"><code>{ "keys": ["gn"], "command": "insert_snippet", "args": {"contents": "\\\~n"} },
  </code></pre>
  
  <p>My expected result with this is:</p>
  
  <blockquote>
    <p>agno ---> a\~no  ---->  año</p>
  </blockquote>
  
  <p>but it lamentably doesn't work...
  Do you know how fix?</p>
