-% $\bS[\dot]{x}^{r}_{\alpha}$, $\bSa[\dot]{E}^s$, etc. These symbols
-% are quite common and variants thereof are found on many

-% \SetSymbFont{\bm}
-%
-% When a subscript is inserted for slanted characters, e.g.,
-% $f^a_b$, the subscript is kerned closer to the symbol.
-% This subscript kerning as well as the superscript height is
-% retained for math accents, e.g., $\dot{f}^a_b$. When
-% the \cmd{\overline} or \cmd{\overrightarrow} commands are used together
-% with math accents, the problems begin\footnote{If you are using
-% Equation Editor or MathType inside word processors in the Windows environment,
-% you end up with the same problems and have to fiddle \myemph{every}
-% sub- and superscript individually. A browse through the accompanying
-% sample document, \pkg{mtsample.tex}, will show that this can amount to
-% hundreds of little equations. I challenge anyone to rewrite that
-% document with one of the popular wordprocessors and still be sane
-% afterwards :-)}:
-%
% \begin{itemize}
-%
-% \item For an \cmd{\overline}, $\overline{f}^a_b$, the superscript moves up to
-% the height of the overline, which is fine for vector notation, but the
-% subscript kerning is lost, because the symbol is set inside a box with
-% italic correction added (App. G of the \TeX{}book). If the subscript is
-% added inside the \cmd{\overline} construct, $\overline{f_b}^a$, the
-% overline is stretched, which is acceptable only when the subscript is
-% part of the symbol itself. The subscript kerning can be corrected by
-% attaching the subscript to the symbol and the superscript to the overline
-% and then overtyping (\cmd{\rlap} or \cmd{\llap}) them while using a
-% phantom symbol (without subscript) for the overline,
-% \begin{sample}
-% |\leavevmode\rlap{$\overline{\phantom{f}}^a$}%|\\
-% | {$f^{}_b$}|
-% \end{sample}
-% which gives \leavevmode\rlap{$\overline{\phantom{f}}^a$}{$f^{}_b$}.
-%
-% The \cmd{\leavevmode} command is nessesary to prevent the symbol being
-% spread over two lines when it is the first token in a new paragraph
-% (\TeX{} in vertical mode).
-%
-% Care must be taken with the sequence in which the two parts overlap when
-% the one is wider than the other,
-% \leavevmode\rlap{$\overline{\phantom{f}}^{abcde}$}{$f^{}_a$},
-% because the superscript will then run into the following text.
-%
-% \item If a math accent is added to the overline, \AccentBox, the superscript
-% goes to the level of the accent (except if the \pkg{accents}\ package is
-% loaded). This can be remedied by controlling the height of the accented
-% overline construction with a \cmd{\vphantom} commands as a strut,
-% \begin{sample}
-% |\leavevmode\rlap%|\\
-% | {$\dot{\overline{\phantom{f}}}{\vphantom{\overline{f}}}^a$}%|\\
-% | {$f^{}_b$}|

-% \item For an |\overrightarrow| in vector notation, ($\overrightarrow{i}_a$,
-% ~$\overrightarrow{iiii}_a\,$), the construction of the stretchable arrow
-% results in an arrow wider than most symbols, with the symbol centred
-% below it. The subscript ended up far removed from the symbol. For
-% multiple symbols, the arrow width is equal to the box containing the
-% letters, resulting in better-looking subscripts (but still without the
-% subscript kerning). The previous procedure can be used to correct the
-% subscript kerning, except that additional white space must be inserted
-% before the symbol to centre it beneath the arrow.
-% \begin{sample}
-% |\newlength{\Wspace}\settowidth{\Wspace}{$\overrightarrow{i}$}|\\
-% |\newlength{\SymWdth}\settowidth{\SymWdth}{$i$}|\\
-% |\addtolength{\Wspace}{-\SymWdth} |\\
-% |\leavevmode\rlap{$\dot{\overrightarrow{\phantom{i}}}$}% |\\
-% | {\hspace*{.5\Wspace}$i^{}_b$} |
-% \end{sample}
-% \newlength{\Wspace}\settowidth{\Wspace}{$\overrightarrow{i}$}
-% \newlength{\SymWdth}\settowidth{\SymWdth}{$i$}
-% \addtolength{\Wspace}{-\SymWdth}
-% which gives \rlap{$\dot{\overrightarrow{\phantom{i}}}$}{\hspace*{.5\Wspace}$i^{}_b$}.

-% The commands can be optimized by using saveboxes, \myemph{but} the
-% symbols will not scale correctly when used as sub- or superscripts or in
-% the \cmd{\tfrac} macro. A solution is to nest the commands inside a
-% \cmd{\mathpalette} environment, but be warned, this is very expensive!
-% The commands \cmd{\phantom}, \cmd{\smash}, \cmd{\overrightarrow} (in
-% \pkg{amsmath}) are already inside \cmd{\mathpalette} macros, and \TeX{}
-% calls the arguments of a \cmd{\mathpalette} macro four times before
-% deciding on the dimensions.

-% \item The shape of the arrow tip of the |\overrightarrow| command was
-% probably not designed for this type of application and is much too broad
-% in the final CM font version. This broad arrow shape is incidentally one
-% of last changes by Prof.~Knuth to the CM font symbols. The PostScript
-% version of the CM fonts typesets the arrow much better, but it is highly
-% likely that it is still the old outdated version of the symbol.
-%
-% \item The subscript heights differ for the cases with and without
-% superscripts, $x_b,\; x_b^a$. This is not very satisfactory for a
-% consistent matrix-tensor notation, but it can be remedied by inserting a
-% dummy superscript, |$x^{}_b$|, which then gives $x^{}_b$, $x_b^a$.
