Using the Start Menu
All the software programs and utilities on your computer are accessed via Windows' Start menu. You display the Start menu by using your mouse to click the Start button, located in the lower-left corner of your screen.
As you can see in Figure 3.8, the Windows XP Start menu consists of two columns of icons. Your most frequently used programs are listed in the left column; basic Windows utilities and folders are listed in the right column. To open a specific program or folder, just click the icon.
Figure 3.8 Access all the programs on your system from the Start menu.
To view the rest of your programs, click the All Programs arrow. This displays a new menu called the Programs menu. From here you can access various programs, sorted by type or manufacturer. (When more programs are contained within a master folder, you'll see an arrow to the right of the title; click this arrow to display additional choices. )
Launching a Program
Now that you know how to work the Start menu, it's easy to start any particular software program. All you have to do is follow these steps:
Click the Start button to display the Start menu.
If the program is displayed on the Start menu, click the program's icon.
If the program isn't visible on the main Start menu, click the All Programs button, find the program's icon, and then click it.
Switching Between Programs
After you've launched a few programs, it's easy to switch between one program and another. To switch to another program (and send all other open programs to the background), you can do one of the following:
-
Click the application's button in the taskbar, as shown in Figure 3.9.
Figure 3.9 Use the taskbar buttons to switch between applications.
Click any visible part of the application's windowincluding its title bar.
Hold down the Alt key and then press the Tab key repeatedly until the application window you want is selected. (This cycles through all open windows.) When you're at the window you want, release the Alt key.
If you have multiple windows open at the same time, you can determine which is currently the active window by its title bar. The title bar for the active program is brighter, and the title bar text is bright white. An inactive title bar is more dull, with off-white text. If you have overlapping windows on your desktop, the window on top is always the active one. The active application's Taskbar button looks like it's pressed in.
