### Setting Up a Konami Feature
```js
// Used for user input keys
keys = []
// Used for the sequence you are listening for
deleteLinkSequence = [38, 38, 40, 40, 13]
// On a keydown event
$(document).on 'keydown', (e) ->
// Push the user entered key into the array
keys.push(e.keyCode)
// Enter will be the final check
if e.keyCode == 13
// String comparison is easier to perform
if keys.toString() == deleteLinkSequence.toString()
// Do stuff
//reset the keys
keys = []
```
