Magnifying the screen is different than just enlarging the text size. This feature is like having a magnifying glass, allowing you to move around by zooming in on parts of the screen.
Click your name on the top bar and select System Settings.
Open Universal Access and select the Seeing tab.
Switch Zoom on.
The Zoom section lists the current settings for the shortcut keys, which can be set in the Universal Access section of the Shortcuts tab on the Keyboard panel.
You can now move around the screen area. By moving your mouse to the edges of the screen, you will move the magnified area in different directions, allowing you to view your area of choice.
You can quickly turn zoom on and off by clicking the accessibility icon on the top bar and selecting Zoom.
You can change the magnification factor, the mouse tracking, and the position of the magnified view on the screen. To adjust these, click the Options button and pick the Magnifier tab.
You can activate crosshairs to help you find the mouse or touchpad pointer. To switch them on and adjust their length, color, and thickness, click the Options button and pick the Crosshairs tab.
You can switch to inverse video or White on black, and adjust brightness, contrast and greyscale options for the magnifier. The combination of these options is useful for people with low-vision, any degree of photophobia, or just for using the computer under adverse lighting conditions. Click the Options button and pick the Color Effects tab.
