Behavior of Backspace & Forward Delete keys

[beekay]

In Horizontal or Vertical layout mode, when an article has focus, the Backspace key deletes the article. However, the Forward Delete key does nothing but generate the "error" beep. I wonder if the Forward Delete key's behavior could also delete the article? This is of course a small thing, but it is convenient, and to me at least, consistent behavior. Thanks for considering.

(PS: also, thanks for changing the behavior of the Return key such that when In Horizontal or Vertical layout mode, when an article has focus, Return opens the article's web page.)
