Review comment (suggestion):
I noticed something with this change. If the user has also a `keys` function in his personal configuration, then he would also have to include the changes here in his personal configuration as well, because the `keys` function only allows the user to modify/extend the default keys. I was wondering why I could not see the key for the `LazyExtras` and when I commented out my own `keys` function it appeared. 

Of course I don't have any more reason to use the `keys` function, since you changed the Lazy key back to `l`, I'm just mentioning it.
