At the very least, they would need to invoke copy and paste capabilities in the application (or in the application's run time system - e.g. Visual Basic), and, in the case of the most often quoted of "screen readers" for web pages, they use MSAA, Microsoft's Accessiblity API, to interface with accessibility support features in the basic browser. Real screen readers tend to be used with tools like Lynx, although they may be quite common amongst those who pay for their own AT.
