With Microsoft Internet Explorer 7/8 you can make Web pages easier to read by magnifying the page (zooming in).But the zoom function can't works in htmlhelp files (chm files) and e-books.

ChmZoomer gives you handy full page zoom functionality in chm files and e-books just like in IE7/8.The shortcut keys are the same as IE and Firefox.Press [CTRL +] or [CTRL Mouse wheel up] to zoom in.

Press [CTRL -] or [CTRL Mouse wheel down] to zoom out.Reset zoom to 100% with Ctrl-0.
