An angular shortcut system based of Zach Snow's blog post: http://zachsnow.com/#!/blog/2013/angularjs-shortcuts/
Shortcuts are english based rather than key codes so you don't have to keep looking them up.
npm install angular-shortcut
In your app:
angular.module('app', ['ng.shortcut'])
Can be used as a directive on any clickable item.
<button ng-shortcut="'enter'" ng-shortcut-click></button>
Or anywhere else:
<shortcut ng-shortcut="'enter'" ng-shortcut-action="someScopeMethod()"></shortcut>
It detaches with scope $destroy so you can use normal ng-if to enable/disable
<shortcut ng-if="somethingIsEnabled" ng-shortcut="'enter'" ng-shortcut-action="someScopeMethod()"></shortcut>
