you can use this.

$("#keyboard").change(function() {
  if ($(this).is(":checked")){
    //your function goes here
  }
});

Check is your checkbox checked inside that function. For example, one of way is to do it this way

$(document).keydown(function(e){
    if (e.which == 65 && $('#keyboard:checked').length > 0){
        $('#test').click();
    }
});

This statement

$('#keyboard:checked').length > 0

checks whether there is more than 0 elements with id keyboard that are checked. You can also check using == 1. Other way is

$('#keyboard').prop('checked') == true

this is written in different manner, but works all the same.
