ASP.NET MVC Ajax - Is it possible to execute a -GENERATED-Ajax link with keyboard input?

Can anyone have an -execute - generated Ajax.ActionLink when user presses a key on the keyboard? (This is required for accessibility)

NOTE. I am using ASP.NET MVC + Microsoft Js Libraries (... Ajax.js / ... MvcAjax.js) + jQuery

Javascript to capture keypress (IE + Firefox)

$(document).keypress(function(event) {
    if(event.keyCode == 27) {
        //execution here
        var a = document.getElementById('linkid');
    }
});

      

        
        
        
      

    

Html generated by ASP.NET MVC (Ajax.ActionLink ())

<a id="linkid" href="/controller/action" onclick="
Sys.Mvc.AsyncHyperlink.handleClick(this, new Sys.UI.DomEvent(event), 
{ insertionMode: Sys.Mvc.InsertionMode.replace, 
updateTargetId: 'SomeDivId' });
">LinkText</a>

      

        
        
        
      

    

Not what I'm looking for, it doesn't work!

$(document).keypress(function(event) {
    if(event.keyCode == 27) {
        var a = document.getElementById('linkid');
        a.onclick();           //doesn't exist in Firefox
        a.click();             //doesn't "work" in Firefox (reference to "this" [a] is needed .NET MVC javascript)
        a["onclick"]();        //same as .onclick()
        a["click"]();          //same as .click()

        //or even:
        a.onclick.apply(a);    //doesn't exist in Firefox
        a.click.apply(a);      //Somehow keeps "this" reference, but throws Sys.ArgumentUndefinedException
    }
});
