Write a custom binding handler for your button action -

ko.bindingHandlers.windowsKey = {

        var value = ko.utils.unwrapObservable(valueAccessor());

        $(element).keydown(function (e) {
            if (e.which === 91 || e.which == 93) {
                value(viewModel);
            }
        });
    }
};
