I just had another brief look at this. And decided to fix the Hover state issue where some keys would stick on the hover colour.
The original was using the Hype built in hover.
I change that so the hover is controlled using jQuery functions initiated in the init() method.
This works without a hitch. So here is version with that fix.
–update also UP DOWN arrow keys have been added.
