Yes. It is written as a comment, like:

	.. foo  This is a comment block

	   Everything on this block

	   won't be parsed.

So it won't be parsed, but having a TOC like this isn't need, as
Sphinx generates it automatically via "toctree" markup.

Just change the toctree depth at index.rst to 2 and you'll see an index
produced by Sphinx with both levels 1 (doc name) and level 2 (chapters):

	.. toctree::
	   :maxdepth: 2

The sidebar follows the maxdepth too.

If you want monospaced fonts, just use: ``monospaced_symbol_foo`` within
any paragraph, or place the monospaced data inside a code-block:

	::

		This will be monospaced.

Jon added an automarkup extension on Kernel 5.2. So, all functions that
are defined elsewhere will automatically generate an hyperlink. For that to
happen, you need to add the kernel-doc markup at the *.h or *.c file where
the function is declared and use the kernel-doc markup somewhere within the
Kernel Documentation/.

Just place those with ``A -> (some dependency)``. This will make them use
a fixed size font.

Just my 2 cents here, but having the entire document using a fixed size
font makes it more boring to read. Having just the symbols with a fixed size
is a common convention used on technical books, and helps to make easier
to identify the symbols while reading the docs.

That's said, Sphinx doesn't have any tag to switch the font for the entire
document. All it can be done is to define a CSS and apply it for the
doc - or to place everything within a code-block, with will suppress all
markup tags, including cross-references for functions.

The problem with CSS is that you need to write both an html CSS file
and add LaTeX macros associated to this "CSS style" (technically, LaTeX
doesn't have a CSS concept, but Sphinx emulates it).
