One of the attractions of Windows 2000 is its ability to run multiple programs at the same time. For every program you open, a button appears on the Taskbar; some programs produce a button for every document that's open.
The easiest way to switch between programs is to click the corresponding button on the Taskbar (Figure 7-1). With each click, you make the corresponding window or program pop to the front.
Figure 7-1. Top: Every window has a Taskbar button. Bottom: Press Alt+Tab to highlight successive program icons. When you release the Alt key, the highlighted program jumps to the front.
Even with a lot of windows open, it's fairly easy to navigate among them simply by clicking buttons on the Taskbar. Sometimes, though, you need to clear the whole screen to get at something on the desktop. That's when you click on the desktop icon, which minimizes all windows, collapsing them to the Taskbar. (The desktop icon, which sits on the Quick Launch toolbar, looks like an old-fashioned blotter.)
Instead of clicking the Desktop button on the Quick Launch toolbar, you can also press Windows key+D.
