As already mentioned in comments

  • The background section of manifest version 2 has to be like

    "background": {"scripts": ["bg.js"]}

There is no background page, only background scripts. So you'll have to move your code from bg.html to bg.js and remove all the extra HTML from it.

  • chrome.extension.sendRequest and chrome.extension.onRequest have been deprecated in favor of chrome.runtime.sendMessage and chrome.runtime.onMessage respectively. That means, you can still use sendRequest and onRequest but it might be subject to removal in a future version of Chrome
  • The keyCode for G is 71 rather than 17
