<p class="commentary">We will call the table opened if the surround is fully visible, in which
case the actual content is hidden but the 8 rows of the table are all
visible; and closed if the surround is hidden, so that only 1 row of the
table is visible, and some or all of the content of the page is visible below.
</p>
<p class="commentary">Each row, except the top one, begins with a rectangle called the sidebar.
If the table is closed then clicking on the sidebar opens it; if it's open,
clicking on the sidebar for a given row closes the table and goes to the
relevant page of the index. The contents of the sidebar cell are defined
by a DIV whose class is "sidebar".
</p>
<p class="commentary">The sidebar is followed by a series of cells called the "boxes", one for
each element in that row's index page. These contain DIVs with the class
"box" and the ID "boxN_M", where N is the row number, 1 to 7, and M is
the column number, 1 to E, where E is the number of elements in that row.
Each box then contains three pieces of text: an abbreviation like Kd,
in a DIV with class "symbol"; a spelled-out name like Kinds, in a DIV
with class "rubric"; and an element number like 3, in a DIV with class
"indexno".
</p>
<p class="commentary">Following that is a broad cell, spanning the rest of the table's width,
which contains text like "Kinds Index". This contains a DIV of class
"headingbox", inside which is a main heading in a DIV of class "headingtext"
and text underneath in another of class "headingrubric".

</p>
<p class="commentary firstcommentary"><a id="SP6_3"></a><b>&#167;6.3. </b>This is called when the user clicks on an element box corresponding to
something on the current page. If that's hidden, we go to state (2) for the
element clicked on. If it's showing, we see which state we're in: if we're
in state (2) we go to state (1), and otherwise go to state (2). (The trick
is deciding what state we're in: we do that by counting the number of visible
elements.)

<p class="commentary firstcommentary"><a id="SP10"></a><b>&#167;10. Links to source. </b>When index files need to reference source text material, they normally do
so by means of orange back-arrow icons which are linked to positions in
the source as typed by the user. But source text also comes from extensions.
We don't want to provide source links to those, because they can't easily
be opened in the Inform application (on some platforms, anyway), and
in any case, can't easily be modified (or should not be, anyway). Instead,
we produce links.
