Question

I am creating a html page which contains a question (a puzzle like situation ). The answer for the question is "Windows 7", but I want the user to get through the question only if he presses windows key followed by 7. I want to create a JavaScript function for this. I am able to capture the individual key press by getting the ASCII value of the keystroke., but when I try to do it in combination its not working. How to go about solving this? Any ideas?

var keys = [];

document.onkeydown = function(evt){    
   var key = evt.keyCode;
   keys[key] = true;
    if(keys[91] && keys[55]){
       console.log("win7");
    } 
}

document.onkeyup = function(evt){    
   var key = evt.keyCode;
   keys[key] = false;
}
