Question

Looking for a way to simulate a multiple keypress using jQuery. For example ALT+F1 (holding down alt and hitting F1).

I’ve managed to simulate the F1 keypress thanks to:
Definitive way to trigger keypress events with jQuery

Looking for something like this:

$(".f1").click(function() {   
    var e = jQuery.Event("keydown");
    e.keyCode = 18; // ALT key pressed
    // while ALT key is pressed, hit the F1 Key
    $("input").trigger(e, function(){
        var e = jQuery.Event("keydown");
        e.which = 112; // F1 key
        $("input").trigger(e);
        });
});

With the modifier keys alt, ctrl, and shift, you can use event modifiers specifically for them:

$(".f1").click(function() {
    var e = jQuery.Event("keydown");
    e.which = 112;       // # F1 code value
    e.altKey = true;     // Alt key pressed
    $("input").trigger(e);
});
