in your diagrams that are not part of any "entry" of the matrix
created by <code>&</code> and <code> \\</code>. This is done with the
<em>excursion</em> command
<P><CENTER><TABLE BORDER=BASIC CELLPADDING=3 COLS=1><TR><TD> <code>\save</code> <I>t</I> <code>\restore</code>
</TABLE></CENTER><P>
<P>
where <I>t</I> should be a target in one of the formats described in
sections <A HREF="node16.html#arrowstargets">2.5</A>-<A HREF="node17.html#arrowschanging">2.6</A>. <I>t</I> can do
any kind of typesetting desired, for example,
<BLOCKQUOTE><PRE>\xymatrix{
A \ar@{-}[dr]
&{}\save[]+<3cm,0cm>*\txt<8pc>{%
This is a very big commentary
but it does not otherwise affect
the diagram.}
\ar[l] \ar[d] \restore \\
& B \ar@{-}[r] & C \ar@{-}[r] & D
}</PRE></BLOCKQUOTE>
will typeset
<P><CENTER><BR><IMG WIDTH=334 HEIGHT=123 ALIGN=BOTTOM ALT="displaymath1007" SRC="img63.gif"><BR></CENTER><P>
It illustrates how a "down" arrow does not necessarily have to point
particularly straight down - in this case because it is based in the
displaced pseudo entry.
