Full list of Windows 7 Keyboard shortcuts

Keyboard shortcuts are combinations of two or more keys that, when pressed, can be used to perform a task that would typically require a mouse or other pointing device. Keyboard shortcuts can make it easier to interact with your computer, saving you time and effort as you work with Windows and other programs

Most programs also provide accelerator keys that can make it easier to work with menus and other commands. Check the menus of programs for accelerator keys. If a letter is underlined in a menu, that usually means that pressing the Alt key in combination with the underlined key will have the same effect as clicking that menu item.
