Yes, that is a compile-time default I set given that Debian / Ubuntu have the
usual 'default' of the sensible-brower wrapper.   What Johannes does is to
simply override this choice to something he likes better.

I suspect you misunderstood this:  "browser" is for the web browser, and only
affects help.start() et al.  What you are looking for is 


as that is used to 'page' the help output.  And I just tried this, so if you do

	options("pager"="kfmclient newTab")

any subsequent call for help will go to Konqueror and R even makes that explicit:

   > ?help
   Help for ‘help’ is shown in browser kfmclient newTab ...
           help("help", htmlhelp = FALSE)
          options(htmlhelp = FALSE)
   to revert.

And this is of course more general than what Johannes said: It'll work
whereever Konqueror is installed, and not just on Kubuntu.  [ Or so I hope,
my test right now was done under Kubuntu Gutsy. ]

Hope this helps,  Dirk
