Moving between open windows and applications Through Keyboard

Moving between open windows and applications Through Keyboard:

To move between any open programs on your computer, press and hold the Alt key, then press the Tab key. If this is done successfully, a window appears that displays each of the open programs on your computer. Repeatedly pressing Tab while continuing to hold Alt moves between each of the open programs. When the program you want to switch to is selected, let go of both keys to make it your current window.
