Hi, list! I've realized the following commands commented in
https://wiki.contextgarden.net/System_Macros/Expansion_Control
no longer work in LMTX:

\@EA
\@EAEAEA
\@EAEAEAEAEAEA

One just could copy them from syst-aux.mkiv, but anyways. Should it be
mentioned on the Wiki or something like that? Thank you very much.

Jairo :)
