Keyboard shortcuts  

Keyboard shortcuts are combinations of two or more keys that perform a task that would typically require a mouse or other pointing device. Keyboard shortcuts
can save you time and effort as you use Windows and other apps. 

Check the menus of apps for accelerator keys. Most of them provide accelerator keys to help make it easier to work with menus and other commands. 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.
With a touch keyboard, you can 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 needed to create shortcuts.
