Thanks, but the Emacs user manual is not the right place for this kind
of information.  Instead, this should be mentioned in the doc string
of term-mode.

Btw, your understanding of this is at least inaccurate if not
incorrect: whether custom key bindings should be added to
term-mode-map or term-raw-map depends on whether you want them for the
line mode or for the raw mode.  The documentation should say so.
