The problem with GUI screen readers, in general is that, unlike a console screen, where there is a fixed memory location which contains the actual character representationsi of the text on the screen, GUI's (M$, Mac, or X) do not have a single array of memory that represents "THE SCREEN" in text form. GUI screenreaders need to intercept application calls to the GUI rendering system, and build / maintain what is sometimes known as an "Off Screen Model" of the display that the screen reader reads from. Compared to that, point and clicking with a keyboard is quite trivial. For links, try searching for the NFB (National Federation for the Blind in the US, or Henter-Joyce (publisher of the Jaws screenreader) or Outspoken (I forget who sells that). aloha, dave
