Many Thanks!
So, a more prolix summary of these things:
@key{DEL} is a _logical_ key, that key which happens to generate ASCII
DEL (0x7f) when you press it. So the sentence "Emacs binds @key{DEL} to
the command @code{delete-backward-char} by default." would be entirely
appropriate.
@key{BACKSPACE} (or @key{BS}) and @key{DELETE} are _physical_ keys,
characterised by their positions on the keyboard or the text embossed
upon them (even though these positions/embossments vary between keyboards
and cultures). @key{BACKSPACE} and @key{DELETE} are thus the appropriate
names to use for the keys that delete in the wrong direction in "@node
DEL Does Not Delete".
The "Equivalent" above means "is configured, whether by the OS's keyboard
setup or Emacs's function-key-map or some other means, to produce the
same keycode as".
I think I've got it now! Apologies to all fellow hackers whose patience
I've stretched in this thread.
