How to replace button click event with keyboard shortcuts - JQuery

In this tutorial I will show you how to replace button click event with keyboard shortcuts using JQuery. Previously, I used button click event I called the JavaScript function for generating the sitemap. Instead of the button event. Here, I m going to implement keyboard shortcuts. 
 This is asp.net MVC project. I have already registered jQuery in Layout page. I have written code for keyboard event. CTRL+ G When these key is pressed I going to call GenerateSitemap() function. The keycode 71 is for Letter 'G'. 
 Here, You can find the list of keycode value for the keyboard press.

jQuery Code:

<script type="text/javascript">
    $(document).keydown(function (e) {
        if (e.ctrlKey && e.keyCode == 77) {
            GenerateSubmitURLs();
        }
    });
    function GenerateSubmitURLs() {
        //Code here..      
    }
</script>
