Hello,
In Math Symbols node one can read the following
--8<----8<----8<----8<----8<-- begin -->8---->8---->8---->8---->8----
@item \leadsto
@BESU{21DD,leadsto} Squiggly right arrow (relation). This is not available in
Plain @TeX{}. In @LaTeX{} you should load the @file{amssymb} package.
To get this symbol outside of math mode you can put
@code{\newcommand*@{\Leadsto at domain.hid@}@}} in the
preamble and then use @code{\Leadsto} instead.
--8<----8<----8<----8<----8<-- end -->8---->8---->8---->8---->8----
Now:
- One could make a similar comment for most math symbol commands, like
\alpha and so on, so why just say that for \leadsto...
- Alternatively to the proposed method one could do:
--8<----8<----8<----8<----8<-- begin -->8---->8---->8---->8---->8----
\newcommand*\OriginalMeaningOfLeadsto{}
\let\OriginalMeaningOfLeadsto\leadsto
\def\leadsto{\ensuremath{\OriginalMeaningOfLeadsto}}
--8<----8<----8<----8<----8<-- end -->8---->8---->8---->8---->8----
and then use \leadsto in whichever mode in {math, text}.
- this is the sole mention of \ensuremath in the whole manual, maybe
this command deserves its own node, and we could just refer to this
node at the top of the Math symbols node.
VBR,
Vincent
