Ability to Edit by using the Enter key.

[ultrablue]

Hi. Great work here, thanks!
I would like to be able to edit an existing item in the list by pressing the Enter key with that item selected (highlighted).
In order to do that, I would also like to be able to use the arrow keys to select (highlight) items.
It's a drag to have to take my hands off the keyboard to edit an existing item.

I'm using Firefox 31.0 by the way.

Thanks!!
Greg
