What documentation?  It's not in the console help screen nor in any R for

think you must be reading some documentation for readline-based systems
under Unix. The R for Windows README says:

Command-line editing is available: see Help | Console for details.

facilities needed for interactive use, including simple command-line

Differences from Unix versions of R

- Command-line editing is always available, but is much simpler than
  under readline-based input on Unix.

so this is clearly documented.

In R version 1.2 you will be able to list the history in a pager and
re-submit commands from there.  Now you can use savehistory() or the
menu item for this to save the history to a file and save it from there.
