This is a directive which can be applied to in order to enable scrolling with the arrow keys in Ionic apps.
Include ion-enable-scroll.js on your page:
<script src="lib/ion-enable-scroll/ion-enable-scroll.js"></script>
Include ionic.enablescroll in your apps dependencies:
angular.module('myApp', ['ionic', 'ionic.enablescroll'])...
Then you can apply ion-enable-scroll to an <ion-content> directive. Be sure to set tabindex="0" to make the <ion-content> focusable:
<ion-content tabindex="0" ion-enable-scroll> ...
And now you can use the arrow keys to scroll your <ion-content>s!
