There’s a question about how to get “LaTeX” symbol in a document, but the answer does not include LaTeX2e.
Searching for “LaTeX2e”, “LaTeX2e lettering” or “LaTeX2e writing” didn’t yield the answer, and neither did trying out the commands \LaTeX2 and \LaTeX2e.
How to set LaTeX2e (and while we’re at it: LaTeX3) in a document?
\LaTeXe(too short to post it as answer). For LaTeX3 use\LaTeX3. – TeXnician May 16 '18 at 15:14\LaTeX2and\LaTeX2ebut didn’t think of\LaTeXe. – Philipp May 16 '18 at 15:16metalogopackage – Michael Fraiman May 16 '18 at 16:07
