Usually in Windows there are more than one way of doing things. You can use a mouse or touch to select items or initiate action.
You can also use Keyboard shortcuts, combinations of two or more keys to perform a task instead of a mouse or touch. Keyboard shortcuts can make it easier to work with your PC, saving you time and effort as you work with Windows and other apps.
Most apps also provide accelerator keys that can make it easier to work with menus and other commands. Check the menus of apps for accelerator keys. If a letter of a word is underlined in a menu, it usually means you can press the Alt key and the underlined key together instead of clicking that menu item. When you’re using a touch keyboard, you can also see some shortcuts when you press the Ctrl key.
Pressing the Alt key in some apps, such as Paint and WordPad, shows commands that are labeled with additional keys that you can press to use them.
An exhaustive list of Keyboard shortcuts is available in the Windows Help documentation at http://windows.microsoft.com/en-us/windows/keyboard-shortcuts#keyboard-shortcuts=windows-8
