I have a button on HTML like:

<paper-button class="button" id="button-wide" raised affirmative on-tap="{{onClick}}">

and in javascript i have function like:

Polymer('dialog', {
        onClick: function() {
            ......
            ......
        }}

And i want fire this button with enter key on keyboard.

Something like this could work:

Polymer('dialog', {
    onClick: function () {
        // etc..
    },
    onKeyDown: function (e) {
        if (e.which === 13 || e.keyCode === 13) {
            this.onClick();
        }
    },
    attached: function () {
        this.onKeyDown = this.onKeyDown.bind(this);
        document.addEventListener('keydown', this.onKeyDown);
    },
    detached: function () {
        document.removeEventListener('keydown', this.onKeyDown);
    }
});

where attached and detached are lifecycle methods of the element.
