Well that's neat! I must study it and learn some of the tricks.
They look useful. The only thing I have against it is that it
doesn't detach from the R window, unlike tkpager which conveniently
does, so it's not possible to continue working in R while reading
help (leaving one as it were helpless ... ).
Thanks, and best wishes,
Ted.
