I simply never saw a keyboard with a "next" key, so I don't know how
it is labeled.  I left those as they were because of that.

They are not inconsistencies to me, because there's a reason for
selecting each spelling, and I explained that reasoning.  Others are
welcome to come up with different schemes, if they want, but I think
in general too drastic changes should be avoided, because people are
used to see "TAB" and "ESC".

If you mention the labels in just one place, it is as if you didn't
mention them at all.  It's a large manual, and no one reads the
section about why the keys are named like they are.  Most readers want
to read what directly pertains to the subject they need now, and
little else.  So the key sequences in the manual need to use a
consistent naming scheme throughout, and not just in some obscure

Sorry, that was incorrect: it should be <LEFT>, in all caps.  The
others are correct.

Before my changes, yes.  Now I see only one, in the Glossary.
