Now for the details of what you can put inside the boxes.
The first thing to notice is that multi-letter identifiers look
better than they do with vanilla L<SUP><SMALL>A</SMALL></SUP>T<SMALL>E</SMALL>X: instead of
<tex2html_verbatim_mark>#math17#specifications, you get <tex2html_verbatim_mark>#math18#<I>specifications</I>.
The letters haven't been spread apart, and the ligature <I>fi</I> has been
used.
<P>
Almost all of the mathematical symbols of L<SUP><SMALL>A</SMALL></SUP>T<SMALL>E</SMALL>X can be used, plus
a few extra ones listed below.
The mnemonics I've chosen may seem a little mad, but that's life.
The L<SUP><SMALL>A</SMALL></SUP>T<SMALL>E</SMALL>X symbols you can't use are the ones whose
names have been redefined:
mostly these are the same symbol, but with the spacing fixed for
use in Z specifications.
First, there are some new arrows, and some new names for old ones:
<BR>
<tex2html_image_mark>#nota78#
<BR>
There are also `accents' <tex2html_verb_mark>38<tex2html_verb_mark> and <tex2html_verb_mark>39<tex2html_verb_mark> which put one and two
crossings repectively over the following arrow.
So <tex2html_verb_mark>40<tex2html_verb_mark> gives <tex2html_image_mark>#tex2html_wrap_inline226#⇧<tex2html_image_mark>#tex2html_wrap_inline227#⇧ and (if you insist)
