ym (i.e. `<font color="#82140F"><code>\.word1.</code></font>', etc.) will behave as
though it were the instance of the original variable or synonym.
<p>
The `<font color="#82140F"><code>&amp;</code></font>' is placed to the left of the variable-name or synonym-name
without intervening space.  For example `<font color="#82140F"><code>foo &amp;.var. &amp;\syn</code></font>' tells
the parser that the newcommand named `<font color="#82140F"><code>foo</code></font>' may possibly alter the
values of the variable
