You are welcome.

They are symbols used in Lisp code, whereas the other kind are words
used in the user documentation.

I disagree.  The manual should make it easier for the reader to
identify the keys it talks about.  For that reason, using the keys'
labels is IMO more useful and efficient than using their lowercase

There should be only these variants in the manual:

  <BACKSPACE>  <Delete>  <left> <Home>

If you find others, please report them as documentation bugs.  I tried
to fix them all, but maybe I missed some; it is a large manual.
