zoom in and out of the screen quickly on a windows pc
If you have difficulty reading what’s on your PC’s screen, you can enlarge everything by activating the Magnifier. You can find this in Settings or by pressing the Windows key + Ctrl + M. Here you can control the standard magnification level from 200% all the way up to 1600%. You can also set the Magnifier to automatically start when you sign into Windows, to invert the colours on your screen to make things easier to see, and how you want the magnifier to operate.
You can turn the Magnifier on by pressing the Windows key + Plus (+) and turn it off again with the Windows key + Esc.

There are three different modes for the magnifier, Full screen where it appears as a floating widget on your screen and the whole screen is magnified, Lens where a floating lens appears underneath your mouse cursor and Docked which places a magnified dock at the top of your screen. The widget also contains Zoom out and Zoom in controls. You can zoom from the desktop using the Windows key + Plus (+) and Windows key + Minus (-).
