Windows+Tab or Alt+Tab
The Windows+Tab combination cycles through the taskbar buttons. When the program you want is selected, hit Enter to switch to that window. If more than one program is running, Alt+Tab brings up the task-switching window. Immediately releasing the keys switches you to the previous application. To jump to one of the other running programs instead, release Tab, but keep Alt held down. Each succeeding press of Tab moves the program selection box to the next application. Releasing the Alt key switches you to the selected program. If only two applications are running, Alt+Tab toggles between them
Ctrl+Esc or Windows
You can use either Ctrl+Esc or Windows to open the Start menu. Use the Up and Down Arrow keys to move through the menu, and the Enter key to choose an item. The two shortcuts vary slightly depending on your version of Windows. Ctrl+Esc, Esc leaves the Start button selected but not pressed. In Windows 95, 98, and NT 4.0 (but not Windows 2000 and ME), Windows, Esc will return you to the window or desktop selection you were working with previously.
Ctrl+Esc, then Esc, followed by Tab, Arrow keys, then Enter
Use this command to go to the Quick Launch toolbar and launch a program.
Windows+M or Windows+D
Use Windows+M or Windows+D to minimize all open windows and reveal the desktop. It’s easy to remember this one: M for Minimize all and D for desktop. Note that Windows+D doesn’t work under Windows 95, but Windows+M does.
Shift+Windows+M or repeat Windows+D
Restore all Windows you previously minimized with Windows+M or (repeat) Windows+D.
Tab, then Arrow, followed by Enter
Move within the Windows Desktop and select items with Tab, then Arrow, and then Enter. Once at the desktop, use the Tab key to cycle through the Start button, Quick Launch toolbar, other toolbars, taskbar button area, and icons on the desktop (and those in the system tray in Windows 2000). Use the Arrow keys to move around within any of these areas of the desktop or taskbar. Use the Enter key to select items. You must, for example, select the Start button to open the Start menu.
