Managing the Windows XP Interface Tip 43 Windows supports a strong data document concept. It is data-driven more than program- driven. If you type a data file (such as a Microsoft Word document) instead of a program name with the Run command, Windows automatically starts the program needed to work with that data file and loads the data file for you. Therefore, you worry less about your programs, and you can concentrate more on your data. In addition, you can type an Internet address (often called a uniform resource locator, or, URL) at Run and Windows XP auto- matically starts your Internet browser and takes you to the Web site you entered. Summary This hour concentrated mostly on the taskbar. The taskbar gives you a play-by-play status of the open windows on your system. As you open and close windows, the taskbar updates with new buttons to show what's happening at all times. If you start more than one program, you can switch between those programs as easily as you switch between cable TV shows: Click a button on the taskbar. The taskbar works along with the Start menu to start and control the programs running on your system. Use the Programs command on the Start menu to start programs with a total of two or three mouse clicks. Although you can use the Run command to start programs, the Programs menu is easier to use as long as the program is set up properly in Windows XP. Q&A Q1: Why would I use the taskbar properties menu to organize my open windows when I can do the same thing manually by dragging them where I want them? The taskbar properties menu gives you the ability to adjust the ap- pearance of your screen's open windows with one mouse click. If you select a cascading window scheme, Windows XP ensures that all open window title bars appear on the screen, with the most re- cently opened window as the front window of focus. You can bring one of the hidden windows into focus by clicking the window's title bar. If, instead, you select the horizontal or vertical tiling options, Windows XP displays a little of all open windows on top of each other or side-by-side. If you normally work in only one window at a time, you won't use the taskbar properties. However, you can use the taskbar properties menu to change the appearance of the taskbar itself. How can I use the taskbar properties menu to change the appear- ance or performance of the taskbar? The taskbar is set by default to appear, no matter what else is on your screen. Microsoft thought it best to keep the taskbar on the screen so that you can switch between programs and adjust the Windows XP performance easily. However, to maximize the screen space and clear away as much as possible, you can change the taskbar's performance so that onscreen windows cover the taskbar, giving you an additional line for the open window. In addition, you can select that Windows XP always hide the taskbar completely, showing you the taskbar only when you point to the bottom of the A1: Q2: A2:
