# Magnifier

The magnifier freezes the screen and shows a magnifying lens under your pointer, for checking
alignment, a blurry icon or a one-pixel gap. Every option is in the
[command reference](/config/cli/glimpse-lens).

## Zoom in

```sh
glimpse-lens
```

The lens opens at three times magnification. Scroll to zoom from 1 up to 200 times; each notch
changes the zoom by about a quarter, and by at least one step. From six times on, a grid shows the edge of every pixel.

To open it closer in, pass `--zoom`, for example `glimpse-lens --zoom 12`.

## Change the lens size

Hold Shift and scroll to make the lens bigger or smaller. It opens with a radius of 180
pixels; `--radius` sets another size, from 10 to 200.

## Move by one pixel

The arrow keys move the lens one pixel at a time, for when the mouse cannot land where you want.

## Close it

Press Esc or right-click. The magnifier prints nothing.
