TeX vs LaTeX

[Sébastien Vauban]

Hi (David?),

I am trying to learn a bit more of TeX and LaTeX, and I am
wondering if it is possible to get the plain TeX primitives
highlighted differently (different color) than the LaTeX ones?

For example, seeing that `\em' is a TeX command, and that
`\textem' a LaTeX one helps differentiating the two layers, and
understanding more of its internals.

Best regards,
  Seb
