Switching Between Programs
After you've launched a program, it's easy to switch between that program and other open programs. You can
Click the application's Taskbar button.
Click the application's title bar.
Click any visible part of the application's window.
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 duller, 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.
