Both Bash and Octave have a nifty addition to the readline library called "operate-and-get-next", bound to "C-o". This function accepts the current line for execution and fetch the next line relative to the current line from the history for editing (see http://www.faqs.org/docs/bashman/bashref_101.html).
This feature has a huge impact in my productivity using Bash and Octave interactively, since it avoids those numerous arrow key strokes in order to rerun a previous block of commands. I looked at the Bash sources and it does not seem too complicate to implement. Octave has borrowed practically the same code from Bash. Before I start looking at the R code, I would like to know whether the R developers had already planned to include the operate-and-get-next feature into R.
