Description
Moved from issue filed by @rpnabar in https://github.com/stan-dev/stan/issues/1636#issuecomment-147490764
@rpnabar says:
When stan_demo() is invoked in R a very long list of examples scrolls on the screen. It is impossible to look at the list since the earlier examples scross off the screen buffer too.
Can we offer a better interface?
Other programs that do this either have hierarchical selection or wait for a key-press after each screenful of info. e.g. while selecting a CRAN or CPAN mirror.
@rpnabar followed up with:
Package: rstan
Version: 2.8.0
Date: Sep 16, 2015
R terminal on Linux Ubuntu
I cannot scroll back possibly because I'm logging in via ssh via Putty and 331 Lines seem a bit too much for Puttys screen buffer I think. I can scroll back to about the 100th example I think.

Research direction
Start by locating the stan_demo() entry point in the RStan package and inspect how its example list is currently printed in an R terminal. Done means users can review the full list without earlier examples scrolling out of view, using a selectable or paginated interface.
