SNIP

True.

However, for what it's worth, FullForm appears straightforwardly in
the Doc Center:

In Doc Center . . .
First section is "Core Language"
First bullet is "Language Overview"
First link is "Symbolic Expressions"
First documented command is "FullForm"

Then a one-liner for ReplaceAll occurs a few lines down. Yes, as you
say, the one-liner needs an edit.

I think this doc structure qualifies Mathematica as sufficiently
"discoverable" [*].
