+\textbf{Introduction.} This document demonstrates a technique designed to
+help people with low vision read material by providing them with a
+convenient way to magnify specific regions of the document. This is
+especially useful for reading technical material such as mathematics, as
+is demonstrated here.
+
+\textbf{Instructions:} Click on any of the mathematics to magnify a region
+around it, the border will blink briefly to focus your attention on it.
+To restore the previous view, click on the region again,
+the formula is briefly highlighted by a blinking border so
+can quickly find your place in the document.
+
+
+\textbf{Sample Mathematical Text.} Consider the problem of numerically
+solving the first order differential equation
+\jdRect*[adddestw=60,adddesth=20]{$y'=f(t,y)$} on
+\jdRect*[adddestw=1in,adddesth=30]{$[t_{start}, t_{end}]$}. Suppose we
+want to classify third order \textsf{Runge-Kutta} type methods. Start with
+\begin{align*}
+\jdRect[height=1.3in,width=2.6in,lift=16pt,shift=-15pt,adddestw=10,adddesth=10] %
+K_1 &= hf(t_n, y_n)\\
+K_2 &= hf(t_n +r h, y_n+aK_1)\\
+K_3 &= hf(t_n +s h, y_n+bK_1+cK_2)\\
+K &= w_1 K_1+ w_2 K_2+ w_3 K_3\\
+y_{n+1} &= y_n+K
+\end{align*}
+Find the system of equations satisfied by
+\jdRect*[adddestw=10,adddesth=10]{$r,s, a, b, c, w_1, w_2, w_3$}
+that will make the above algorithm a third order method.
+
+\textbf{Inline links.} Links can be provided within the text to jump to a
+magnified region that needs to be inspected more closely. The links below
+are different from the ones above. After jumping to a magnified rectangle,
+restore the preview view by clicking on the rectangle.

+is also known for his work on airfoils.
