the final say over how a particular element on his or her page looks when it's focused. By default, elements have the appearances I describe in the following list, but the designer can override the appearance. For example, some designers indicate a focused link by bolding the text of the link instead of using a dotted rectangle. Because hundreds of possible styles are available for a designer to use, I can't cover them all; it's just something to watch out for. Fortunately, most designers stick to the tried-and-true defaults in the following list: Web pages themselves: As strange as it sounds, the Web page itself (the Content area) can have focus. You can scroll the focused page by using the arrow keys, or select text by holding Shift+< or Shift+> (depending on the direction in which you wish to select). When text is selected, you can use the keyboard shortcuts listed in Table B-3, earlier in this appendix. Tip When the Web page has focus, a particular portion of the page actually has the focus. Which portion is focused controls where selection begins when you use the text selection method I describe. To see which part of the page has focus, you can turn on a flashing cursor, just like the flashing cursor you see in focused text boxes. This is called Caret Browsing, and you can activate it by pressing F7, or by setting an option in the Advanced category of the Options window, as I discuss at the end of Chapter 16.   Firefox focuses a page automatically when it finishes loading. If you then focus the Search Box or the Location Bar (by clicking within either), you can restore focus to the page by pressing the Tab key once or twice, or by clicking an empty spot within the page. Unfortunately, the Web page is the only element that doesn't indicate when it has focus (a bug we developers hope to fix soon). Try ^ and v; if the page scrolls, it has focus. When the page has focus, pressing Tab focuses the first element within the page. Pressing Shift+Tab focuses the Search Box in keeping with the reverse Tab order of right to left, bottom to top. Links: When a link has focus, its text is surrounded by a dotted, rectangular border, as shown in Figure B-5. You can load the Web page pointed to by the focused link by pressing Enter. To load the page in a new window, press Shift+Enter. To load the page in a new tab, press Ctrl+Enter (Windows) or +Return (Mac). (Just as when you open a link in a new tab using the mouse, the new tab is not automatically selected.) To save the linked page to your computer instead of following the link, press Alt+Enter (Windows) or Option+Return (Mac), and then select a destination and filename in the window that appears. Figure B-5: A flock of focused elements. Buttons: When a button has focus, its text is surrounded by a dotted, rectangular border, as shown in Figure B-5. You can click the focused button with the keyboard (execute whatever command the button executes when clicked) by pressing the spacebar. Drop-down lists: When a drop-down list has focus, its text is surrounded by a dotted, rectangular border, as shown in Figure B-5. You can cycle through the other items in the focused list one-by-one, upward or downward, by pressing the up- or down-arrow keys. You can cycle through the list in intervals of 20 by pressing Page Up or Page Down. If the list has fewer than 20 items, Page Up selects the first item in the list, and Page Down selects the last. You can also press Home to select the first item or End to select the last, which works even in lists of more than 20 items. Regular lists: When a regular list has focus, the selected item in the list is surrounded by a dotted, rectangular border, as shown in Figure B-5. Because the selection color tends to be dark, this border can be hard to see, but it's there if you look closely. You can select another item in the focused list by pressing the up or down arrow until you reach it. To navigate the list
