Answer 1

Here you go

var e = jQuery.Event("keypress");
e.which = 43; // # Some key code value
$(document).trigger(e);

Answer 2

$(document).on('keypress',function(e) {
    if (e.keyCode == 43 || e.which == 43) {
        var identifier = e.target.id;
        console.log(e.target.id);
        $('#' + identifier).click();
    }
});
