  5. Site list - lower window. CRA sections and their sub-sections associated with the search term are displayed here. You may select a listing and then double-click or click the arrow (go) button to go to the link. If a link is selected, its corresponding URL is displayed in the browser's status line (just like when your mouse is over a link in a normal web page).
