Google has added an opt-in features called “Accessible View” to their Experimental Search page. When you join, you’ll see a blue focus box around individual search result items in Google web search. You can then use the up and down arrows on the keyboard to select different items, and hit enter to go to the specific page. The blue focus box is “magnified to aid low-vision users,” Google says, and that “if you are using a screenreader ... you will hear the relevant information spoken automatically as you navigate.” Google notes that you’ll need Firefox 3 to use all of these experiment’s features.
