‚Äčthis is an impossible request.

i think the description for both the "region" keyword as well as the "near"
keyword are concise and the concepts simple and straightforward.
so if you have difficulties here, you will first have to explain what it is
that confuses you.
since i don't see anything confusing in the explanation for those two
keywords, any explanation of what these do would be the same as what is
already given in the documentation.
