That's a pretty remarkable achievement when you consider all the things you can do with your mouse in a Web page alone: Select text on the page, click buttons and links, and select items from drop-down lists, among other things. All this is easy with a mouse because you can target the element you want to interact with using the mouse pointer. Because you don't have this luxury when you're using the keyboard, you must first focus the element you want to interact with. Throughout this appendix, you can find a number of references to focusing and you might have wondered whether I've lost my mind. In fact, even though you might not have heard the term, the concept of focus is common to all software programs, and you use it all the time. When you focus an element (such as a text box or a Web page link), you are simply indicating that you want to work with that particular element by using the keyboard. For example, when you focus a text box, a flashing cursor appears in the box, and now you can begin typing. This example points out the three main questions that pertain to focusing: How do you focus an element with the keyboard? How does an element indicate when it has focus? What can you do with a focused element? To answer the first question, you must be familiar with the concept of Tab order. When you target an element on a Web page with the mouse, you probably don't give much thought to how the page is oriented. You don't need to: The mouse pointer allows you to reach any element easily. However, the keyboard offers much less freedom, and so reaching an element takes much longer. You must focus element by element until you reach the one you want. You do this by pressing Tab repeatedly. Elements are focused in a left-to-right, top-to-bottom fashion (approximately), as I demonstrate in Figure B-4, and this is called the Tab order. To navigate elements in reverse Tab order (in a right-to-left, bottom-to-top fashion, approximately), you press Shift+Tab. The reason I say these orders are approximate is because unfortunately, Web designers have the final say over the Tab order of elements on their pages. Don't be surprised if the ordering seems erratic sometimes. Figure B-4: Press Tab until the element you want to work with is focused. REMEMBER Only one element can have focus at a time. The concept of focus is not limited to Web page elements; it extends throughout the Firefox interface. For example, clicking within the Location Bar focuses the bar so you can enter an address, and whichever element currently has focus (even if it's part of the Web page) loses focus. To know when the element you want to work with is focused, you need to know how that particular type of element indicates focus. Of course, you'll also want to know what you can do with the focused element. Because each of these things varies among elements, I include a list of focusable elements in this section.
