I don't understand: "Case" tells everything that "Fixing Case" tells,
and then some.  By contrast, "Fixing Case" describes only a small part
of what "Case" describes, and it does that to avoid the need for the
reader to read the entire large section in "Case" when all they are
interested in is how to fix letter-case typos.

If we added a cross-reference to "Case" to "Fixing Case", what would
that add to what "Case" already describes?  If it doesn't add
anything, then a reverse cross-reference would not be useful.
