After

\def\MyText{\textbf{My Text}}
\let\MySaved\MyText


\MySaved and \MyText have the same \meaning. What I would like to have further down in the document is

% \MyText = \textbf{My Text}
\def\MyText{\textit{More Text}}
\let\MySaved{\MySaved \MyText}
% \MySaved = \textbf{My Text} \textit{More Text}


but obviously \let does not allow a group of tokens in the second argument.

Is there any way to append like this with the same specific (non-)expansion properties \let has?


Question: Is it possible to get a popup to ignore MenuDropAlignment in a WPF / Touch app?
Answer: Set it to regular mode for your whole application:

        FieldInfo fi = typeof(SystemParameters).GetField("_menuDropAlignment",
           BindingFlags.NonPublic | BindingFlags.Static);

        fi.SetValue(null, false);
