title: How do I change the font selection in a GMail compose window from JavaScript?
body: <p>I often mention code in my e-mails, which I like to make visually distinct from the rest of the text. It's a huge pain to do this with the current UI, though.</p>
  
  <p>I want to make a Chrome extension which adds a keyboard shortcut to toggle the font in the GMail compose window to 'Courier New' and back to 'Sans Serif'. This seems relatively hard since all the JS code is obfuscated.</p>
