If you want to return to a page you went to as a result of a successful search from the Google search field, click the magnifying glass in the search field to get a list of your recent searches. Select the one you used the last time to see the Google suggestions again.

A search from Safari's convenient Google search field provided a long list of promising hits on the Google results page. You click on one, and then click a link on that page, and then another link...and eventually reach a dead end in your search. To get back to the results page quickly, just click on the orange SnapBack button in the Google search field.

The search field in an application's Help menu lets you find things listed in the program's other menus. Many of the places you've been in Safari are listed in its History and Bookmarks menus. Put these two facts together, and it means you can type part of a Web page's name into Safari's Help menu search field to easily find a page that is listed in either menu, or even in the History menu's submenus.
