Cannot use the keyboard

[rossburton]

I can't enter numbers of operators using my keyboard.

not sure what to do about this...

This app is designed for use with a touch screen, eg mobile phone, tablet, and laptop (eg Lenovo X1 Carbon). However, it would be nice to be able to get it working with a h/w keyboard; but I'm not sure how to do that exactly :

1. perhaps the lower lcd could be a text input element - would need to be styled appropriately in order to minimise visual impact
2. perhaps keyboard input could be captured by a hidden text input element, and so there would be no visual changes at all

I do not require the scientific options. So I will do be doing it for my use case using the mousetrap library. If you find time before me feel free to do the whole mapping.

My current hack after including moustrap is:

    Calculator = new function() {
        Mousetrap.bind('0', function() {
            $('#button0').trigger('mousedown');
        });

        Mousetrap.bind('1', function() {
            $('#button1').trigger('mousedown');
        });

        Mousetrap.bind('2', function() {
            $('#button2').trigger('mousedown');
        });

        Mousetrap.bind('3', function() {
            $('#button3').trigger('mousedown');
        });

        Mousetrap.bind('4', function() {
            $('#button4').trigger('mousedown');
        });

        Mousetrap.bind('5', function() {
            $('#button5').trigger('mousedown');
        });

        Mousetrap.bind('6', function() {
            $('#button6').trigger('mousedown');
        });

        Mousetrap.bind('7', function() {
            $('#button7').trigger('mousedown');
        });

        Mousetrap.bind('8', function() {
            $('#button8').trigger('mousedown');
        });

        Mousetrap.bind('9', function() {
            $('#button9').trigger('mousedown');
        });

        Mousetrap.bind('.', function() {
            $('#buttondot').trigger('mousedown');
        });

        Mousetrap.bind('+', function() {
            $('#buttonadd').trigger('mousedown');
        });

        Mousetrap.bind('-', function() {
            $('#buttonsubtract').trigger('mousedown');
        });

        Mousetrap.bind('backspace', function() {
            $('#buttondelete').trigger('mousedown');
        });

        Mousetrap.bind('enter', function() {
            $('#buttonequal').trigger('mousedown');
        });

        Mousetrap.bind('c', function() {
            $('#buttonclear').trigger('mousedown');
        });

        Mousetrap.bind('*', function() {
            $('#buttonmultiply').trigger('mousedown');
        });

        Mousetrap.bind('/', function() {
            $('#buttondivide').trigger('mousedown');
        });

        this.localizer = null;
        this.parser = "";

This needs to be refactored in to a key map and single method.
