Chapter 24 Accessibility 1263 In the Internet Options dialog, click the Advanced tab. This opens the dialog depicted in Fig. 24.44. The first available option is labeled Always expand ALT text for images. By default, IE5.5 hides some of the text if the size of the text exceeds that of the image it describes. This option forces IE5.5 to show all the text. The second option reads: Move system caret with focus/selection changes. This option is intended to make screen reading more effective. Some screen readers use the system caret (the blinking vertical bar associated with editing text) to determine what to read. If this option is not activated, screen readers might not read Web pages correctly. Web designers often forget to take accessibility into account when creating Web sites, and, in attempts to provide large amounts of content, they use fonts that are too small. Many user agents have addressed this problem by allowing the user to adjust the text size. Click the View menu and select Text Size to change the font size in pages rendered by IE5.5. By default, the text size is set to Medium. In this chapter, we presented a wide variety of technologies that help people with various disabilities use computers and the Internet. We hope that all our readers will join us in emphasizing the importance of these capabilities in their schools and workplaces. Well, that s it for now. We sincerely hope that you have enjoyed learning with C# How To Program. As this book went to the presses, we were already at work on Advanced C# How To Program, a book appropriate for professional developers writing enterprise applications and for students enrolled in advanced software-development courses.
