I know very well about TeX primitives and the asterisk.
Some misunderstandings seem to lurk here.
Example: Consider a TeX version TeX- that agrees
with TeX let alone the fact that TeX- doesn't have
the primitive \gdef. TeX- then behaves like TeX
if you include \def\gdef{\global\def} in your macros.
This is why I consider \gdef a "hard-wired shorthand"
for \global\def.

In my example I asked for a macro for which
\accent is a "hard-wired shorthand" in the previous sense.

I reached out for a "really comprehensive" manual --
as opposed to a "quite comprehensive" manual -- this is why
I have posted this indeed -- indeed -- indeed ! -- !! --- !!! ... ... ...
Got it? Got it?? Got it???

Indeed I wanted to learn about such errors!
