[texhax] the \let command

[R.Tange at soton.ac.uk]

The last solution works fine.

Note that the line
\newcommand{\tiedindeed}[1]{{\let\t\tie \t#1}}
can be replaced by
\newcommand{\tiedindeed}[1]{{\let\t\tie \tie#1}}
and that you can move the line
\renewcommand{\t}{\textit{t}}
to the end.

Anyway, for me the problem is solved.

Thanks a lot,

Rudolf
