trouble with any embedded sound is it is inaccessible to a large population without sound cards or the appropriate platform no matter what audio format you use. Trouble with real audio is that it is not available to all platforms and even on those that it is available for, requires additional software/plug in. best audio is .wav or other native formats since they require only the existing built in processors. ----- Original Message ----- From: "Jon Gunderson" <jongund@uiuc.edu> To: "Ian B.

Spatial keyboard access (where the user moves the pointing device "in space" via the keyboard) is required for functionalities that cannot be made available by direct or sequential access. For example, when the position "in space" is an important part of the functionality (i.e. a program to manipulate a bit-mapped image). In most cases the direct and sequential access techniques will be redundant with spatial techniques associated with a pointing device. Furthermore, the user agent should satisfy this requirement by offering a combination of keyboard-operable user interface controls (e.g., keyboard operable print menus and settings) and direct keyboard operation of user agent functionalities (e.g., a short cut to print the current page). As examples of functionalities, ensure that the user can interact with enabled elements, select content, navigate viewports, configure the user agent, access documentation, install the user agent, operate controls of the user interface, etc., all entirely through keyboard input. It is also possible to claim conformance to this document for full support through pointing device input and voice input. See the section on Input modality labels.
