Keycodes incorrect 

The type definitions for keys have a few incorrect entries on my machine (windows 10). 

```
  // Enter: 28,
  Enter: 3612,
  // Backquote: 41,
  Backquote: 125,
```

Above you'll find the expected code's, versus the actual output when I log the event.

I can't see where the types are actually defined, otherwise I would open a PR.
