Sample slides update

On the first slide, enhance the basic keys help message. The previous
message was too brief for some users.

Make the script slide clearer. The text now explains that the slide is a
script, which now provides interactivity to highlight it. Add comments
in the script sources to notify that it has been printed once the script
has been completed.
