@TeX{} (TeX) and @LaTeX{} (LaTeX) ¶Use the @TeX{} command to generate ‘TeX’. In a printed
manual, this is a special logo that is different from three ordinary
letters. In other output formats, it just looks like ‘TeX’.
Similarly, use the @LaTeX{} command to generate ‘LaTeX’,
which is even more special in printed manuals (and different from the
incorrect La@TeX{}. In other output formats, the result is just
‘LaTeX’.
The spelling of these commands is unusual for Texinfo, in that they use both uppercase and lowercase letters.
