Keyboard Shortcuts That Take Place of a Mouse

These shortcuts are only good for Windows users. Windows + Up and Windows + Down -- they change the screen view, you can either zoom in or zoom out

Windows + Shift + Up and Windows + Shift + Down -- they change the view of the screen, the width,  and height

Windows + Left and Windows + Right -- they control the page of the screen, so if you want it to appear half of it to one side, then you direct it to that side.

Windows + Home -- this controls or sends you to your desktop screen

Windows + E -- Opens up a new Explorer Window
