When the autoactivate attribute is not specified for a list, the viewer must press the GO button on the remote control (or Return on a keyboard) to activate the list and select an item from it. Also, when autoactivate is not specified, the arrow buttons on the remote control move the Highlight rectangle to the next selectable item on the web page.
When the autoactivate attribute is specified for a list or when the viewer has activated the list, the viewer can use the arrow buttons to move up and down within the list. The viewer can select an item by pressing the GO button.
