Much of your experience while navigating the activation wizard depends on optimizing the configuration of your screen reader. Using Window-Eyes as an example, the Verbosity group setting, "read entire dialog," is not turned on by default, and we recommend you do so.
In the JAWS screen reader, the screen echo setting should be changed from Highlighted to All. We have done this for you in the configuration file that accompanies the Activation Wizard (actwiz.jcf).
You should take full advantage of your screen reader hot-key for speak-all or read active window. Under Microsoft Windows, the activation wizard window is fully read aloud only when the wizard has just become active after the focus has been on another window. When you use the NEXT or BACK button to go from one page to the next, this is a change within the wizard, not a new window, so the next page is not automatically read, and the hot-key prompt becomes vital to know what is going on.
You can navigate to -- or away from -- a group of radio buttons using the TAB key, but you need to use the ARROW keys to navigate to, and set, the individual radio buttons within the group.
When you select a task that requires elevated privileges, expect to have the UAC dialog pop up after you click the NEXT button on the Main page. When you OK that dialog, the Wizard will come back in focus.
