Getting basic data from Ruby itself?

I'm building my study tools for the Ruby certification exam. Is there a
way to query Ruby itself for:

Key words (def, begin, end, etc)
What those key words do
The list of built-in modules and classes
The standard library modules

Some things seem to have ri documentation, some I just haven't figured
out how to get yet. I do not want a web page with the data, but a web
tutorial on how to get it would be great.

Thanks!
