Getting Out of Trouble Without the Mouse

It is possible to get out of messages and applications without the mouse.
The first thing to try is the Escape key. This will get you out of messages, emails and dialogue boxes.
To close an application, press Alt + F4.
Or press Alt + F for the File menu and press the Up Arrow until you get to Close or Exit, then press Enter.
The next step is to close down the PC.
I usually press Windows + X, then the letter U twice.
Or you can press Windows Key + D for the Desktop, then Alt + F4, then Enter.
The last resort is to press and hold the power button, but try everything else first!
