Working with Office
Many dialog boxes feature notebook-style "tabs," where each tab offers a single "page" of options. To move from page to page in a "tabbed" dialog box, all you have to do is click a tab with your left mouse button.
You can also navigate tabbed dialog boxes with the keyboard, as follows:
Press Ctrl+Tab to move to the next tab in the dialog box.
Press Ctrl+Shift+Tab to move to the previous tab in the dialog box.
