Use jQuery to click an element while triggering css :active

I have a button div:

<div id="hud-button1"> </div>

I attached a listener to it:

$('#hud-button1').click(function(){ //Do Stuff });

And it has a CSS :active rule:

#hud-button1:active { /* .. */ }

So far so good. Now i want to add the option to trigger this button by pressing a key:

window.onkeyup = function(e) {
    var key = e.keyCode ? e.keyCode : e.which;

    if (key == 87) { $('#hud-button1').click(); }

While this works, i want the button to show the small "animation" it plays via the :active rule.

I am aware that i could add a class and remove it quickly, but the button will be mashed quickly and a lot, so im afraid that the Timeouts would interfere and bug. Is there any clean solution to this? Thanks in advance.


Thank you for your help, i solved it exactly as proposed, a class similar to the :active selector is being attached on keydown and removed on keyup.

That way it feels very responsive and no timeouts interfere.

$( document ).keydown(function(event){
    if(event.keyCode == 81){

    $( document ).keyup(function(event){
    if(event.keyCode == 81){
