Lightning Magnifier Help
Lightning is an easy-to-use screen magnifier for Microsoft Windows: it makes things on the screen bigger and easier to see for people with problems with their sight.
Use the + and - buttons to zoom in and out, and adjust how it looks by using the other buttons and opening Settings.
Zoom level is how much magnification is done. At higher levels you can see things bigger but it is harder to find your way around the screen.
- By default Lightning magnifies the same amount horizontally and vertically. You can have different magnification for each: use the X=Y section in Settings on the Settings tab.
Invert inverts the display: black becomes white, white black and so on. Some people will find inverted screens easier to see.
Style means how Lightning magnifies: the whole screen, or a lens on the screen are the most popular options, but you can also have a magnified strip that follow the mouse cursor, or have one half of the screen magnified while the other is not.
- Full fills the screen with a magnified view. This gives you the most space magnified, but you can lose track of where you are.
- Split divides the screen, part magnified and part not. Look at the magnified section to make things out and the non-magnified section to work out where your mouse cursor is.
- Lens has a smaller magnified area follow your mouse cursor. Easiest to keep track of where you are, smallest magnified area. Change the lens size with the buttons in the Style section.
- Line produces a magnified line that follows the mouse cursor. Good for reading text but otherwise using the mouse as normal.
Tracking controls how Lightning changes where on the screen it is looking when things happen. You may find it better to have Lightning only follow the mouse cursor, or you may want it to follow as you type.
- Track Caret means Lightning follows as you type. This is handy because you can keep the text you are writing magnified.
- Track Window means Lightning moves to new windows as they come up. This is good because it helps you follow along as things happen on the screen, but it does mean Lightning jumps around.
- Track Focus means Lightning moves as you tab around windows, from button to button. This is mainly useful for people who don't use the mouse.
By default the mouse cursor is kept in the middle of the screen. You can make the screen move about less by selecting Border for Scrolling on the Pointers tab.
- Centered keeps the mouse cursor in the middle. Easiest to find it.
- Border means the magnified area doesn't move until the mouse cursor gets near the edge. This means the magnified area jumps around less, so it might be easier to see.
You can also use the following shortcut keys while Lightning is running:
- Close Lightning with Control and Q.
- Zoom in with Control and the + key.
- Zoom out with Control and the - key.
- Open settings with Control and L.
