Hmm, since this thread seems to perpetuate .. let me take the opportunity to explain how enormously nicely (:-) this is achieved in ESS (Emacs Speaks Statistics):

  1. ?plot opens a separate emacs buffer with the help page.
  2. and emacs gains a separate "ESS-help" menu.
  3. From that menu you can learn that you can very quickly move around in the help buffer using "n"(ext) and "p"(revious) or skip to a section via "s <letter>." Now the most used keystroke in ESS help buffers I use is "s e" := "[S]kip to the [E]xamples section".
  4. Inside the examples section, 'l' (single lowercase "L" for [L]ine) sends single lines to the running *R* process, or 'r' sends a whole [R]egion (that you typically have marked with the mouse).

Since it seems that there are ESS users who don't know about this feature, I'm also CCing this to ESS-help.

(and yes, I could go on: You can also send code from the  examples when *editing* the *.Rd (R help) files ...)
