No, the info.info manual is not what I had in mind.  I meant the Emacs
manual.

I think a good place is to mention this feature in the "Misc Help"
section.

First, please leave 2 spaces between sentences, and use "--" for a
dash.

More importantly, "pointing to help documentation" is confusing: what
exactly is "help documentation" here, and how does an Info manual
"point" there.

I think you should instead say that these symbols are made into
buttons that can be used to display the documentation strings of the
functions/variables.  Or something to that effect.

Thanks.
