The appearance in Info _is_ implementation.

Go back and re-read your report.  Then look up the corresponding
portions of the manual, and you will see that <RET>, <F1> etc. are
used in the context that names keys by their names.

If you are saying that sometimes <..> is used where we talk about
keyboard input, then please point out specific instances where that
happens, instead of making a general observation.  As a general
observation, what you say is incorrect.

Which cases, specifically?  Your reference is to an entire node.

You made nothing clear about that, till now.

Thank you!  We have hope!

"use" is a grey area.  What about the following sentence:

  To end a line, press the <RET> key.

?  Are we naming a key by its label or are we talking about a "key
sequence"?

@address@hidden

If you don't understand Texinfo and don't care about the other output
formats, your report is not of much use, because changes to the manual
_must_ consider all supported forms of output.

Not "just".  There's a fundamental difference: "A" is a key and a
character; <RET> is "just" a key.

No.

Yeah, right.  _I_ am making a big deal.

When it's clearly part of a sequence of inputs, yes.

Exactly where?  Be specific, if you want any result other than
"wontfix".
