+<h1><font size="-2">Hypertext Help with LaTeX</font><br><font color="#cc0000">Subscripts</font></h1>
+<p>
+ To get an expression, <tt>exp</tt>, to appear as a subscript, you just type
+ <tt>_{exp}</tt>.<p>
+ Can be used only in <a href="ltx-115.html#math">math</a> mode.
+ Thus, for a simple expression that is part of the running text:
+<pre>
+ <tt>H$_2$O is the formula for water</tt>
+</pre>
+should display as "H<sub>2</sub>O is the formula for water".
+Note that the braces around the argument may be omitted if the
+subscript is a single character.
+<p>
+If a symbol has both subscripts and superscripts, the order doesn't matter.
+The following are equivalent:<br>
+<pre> <tt>a_n^2</tt> and <tt>a^2_n</tt></pre>
+<p>
+Subscripts are normally displayed in a smaller font; to prevent this and,
+for example, use a standard Roman font, one would use;
+<pre>
+ <tt>$J_{<a href="ltx-304.html">\rm</a> Roman}$</tt>
+</pre>
