Here's a sample of a web page as displayed in Internet Explorer with MathPlayer. Almost all of MathPlayer's special features are accessed by placing the mouse pointer over an equation and clicking the right mouse button, as shown on the picture. Choose the MathZoom command (or left-click on the equation) to get a closer look at the equation. This can be handy to view small scripts and accents.
