Universal Access is a black box product. This means that it has been designed from the outset to be extremely flexible with the ability to change many aspects of its functionality at runtime simply through configuration. Many other aspects can be modified by using the UA APIs. If, after reading this guide, you are still unable to do what you require, then you can request a feature in a Service Pack or other future release. By choosing this route the feature you are getting will be incorporated into the product with all the testing and quality assurance that this implies.
