Angular service for keydown detection
npm install angular-keydown
  
Sometimes, it could be useful to detect a pressed key during a click or another event. Let's say you have a validation button. It would rock if it pops up a confirmation message when you click on it, but not if you hold the shift key, right ?
Angular-keydown makes it really easy!

``javascript
angular.module('', ['msieurtoph.ngKeydown'])
.directive('myTest', ['Keydown', function(Keydown){
return {
restrict: 'A',
link: function(scope){
scope.click = function(){
if (Keydown.shift){
scope.message = 'Shift key has been pressed when clicking!';
} else {
scope.message = 'Shift key nas not been pressed when clicking!';
}
};
}
}]);
});
`html
`
The service lets you know whether the following keys are pressed :
* shift, ctrl, alt
* , down, right, left arrowspgUp
* , pgDown
* , escape, enter, tab
For other keys you can look to Keydown.others[_theKeyCode_]
For instance, will equal true if the a key is down.
Keydown.pressed gives you the list of pressed keys.a
For instance, if , b and c keys are down, Keydown.pressed will equal [65, 66, 67]`
