Keyboard Shortcut, Open New Window [Chrome Extension]

I'm trying to develop a Chrome extension where you press a keyboard shortcut and the URL will load in a new window, but I can only get the URL to open in the same tab.

开发者_Go百科script.js

if (window == top) {
    window.addEventListener('keyup', doKeyPress, false); //add the keyboard handler
    }
    var post = "urlhere.com";

    var trigger_key = 85; // u key
    function doKeyPress(e){
        if (e.altKey && e.keyCode == trigger_key) {
            chrome.extension.sendRequest({redirect: post});
        }
    }

background.html

<script>
chrome.browserAction.onClicked.addListener(function() {
    var w = 440;
    var h = 220;
    var left = (screen.width/2)-(w/2);
    var top = (screen.height/2)-(h/2); 
    chrome.windows.create({'url': 'redirect.html', 'type': 'popup', 'width': w, 'height': h, 'left': left, 'top': top} , function(window) {
    });
});

chrome.extension.onRequest.addListener(function(request, sender) {
        chrome.tabs.update(sender.tab.id, {url: request.redirect});
    });

  </script>

So far, all of the above works, the specific url will display, but in the same tab. Is it possible for it to display a a new (popup) window? I've tried numerous amounts of coding, but no such luck.

I tried this, but it did not work

(window == top) {
    window.addEventListener('keyup', doKeyPress, false); //add the keyboard handler
    }
    var post = "urlhere.com";
    var w = 440;
    var h = 220;
    var left = (screen.width/2)-(w/2);
    var top = (screen.height/2)-(h/2);  
    var trigger_key = 85; // u key
    function doKeyPress(e){
        if (e.altKey && e.keyCode == trigger_key) {
chrome.browserAction.onClicked.addListener(function() {
    chrome.windows.create({'url': 'redirect.html', 'type': 'popup', 'width': w, 'height': h, 'left': left, 'top': top} , function(window) {
    });
});     
        }
    }

I use this function for opening in a new window:

function openInNewWindow(url) {
   var newWindow = window.open(url, '_blank');
   newWindow.focus();
}
