[ESS] shift-return key binding on ESS Wiki, .R versus .Rnw

[Erik Iverson]

David,

I did not test this at all, but to get started, I notice
there is a variable called Rnw-mode-hook, which is run before
entering a buffer into Rnw-mode. So you could try as a first
step:

    (add-hook 'Rnw-mode-hook
          '(lambda()
             (local-set-key [(shift return)] 'my-ess-eval)))

Hope that helps,
--Erik
