gistfile1.js

// Route multiple form elements to a single method to handle key presses in Angular
//ng-keypress="checkKey($event)"

$scope.checkKey = function(e){
  if(e.charCode === 13){ // 13 = Enter
    switch(e.currentTarget.name){
      case 'elementName':
        $scope.doThing();
        break;
      case 'elementTwo':
        var item = angular.element(e.currentTarget).scope().item;
        doOtherThing(item);
        break;
    }
  }
};
