Newbie Question : Making Sections Visible

[Junoexpress]

Hi,

I saw a presentation recently where the speaker presented the basic
sections of his talk:
1) Intro
2) Problem ,... ect

He had the presentation set up in such a way that as he stepped
through the presentation slide by slide,
on each slide off to the left the list of topics was present and the
one he was currently on was highlighted.

It looked really cool and it also gives the audience a sense of "where
they're at" in the talk, so I'd like to incorporate it into my next
presentation. How do you do this?

TIA,
Matt

Maybe (there are several ways to do this) he had a different master for each
section and the master incorporated the corresponding highlighted section
