Magnifier - Controls
These controls work while the magnifier lens is open. Some depend on the capture method; see How the lens moves.
- Scroll wheel: scroll up to zoom in, scroll down to zoom out.
+and-keys: zoom in and out (Magnification API only).
Each scroll step changes the zoom by the Zoom Step Size. Zoom stays between the Minimum Zoom and Maximum Zoom settings. See Settings.
Resize
Section titled “Resize”Hold Ctrl and scroll to make the lens larger or smaller. Each step changes the size by the Size Step (px) setting, and the lens stays between 50 and 600 px.
Press the arrow keys, or W, A, S, D, to move the lens in small steps without moving the mouse. Each press moves the lens by the Nudge Distance (px) setting. Nudging is available with GDI+ Capture.
With GDI+ Capture, drag the outer ring of the lens to move it. The cursor changes to a move cursor over the ring. The Drag Border (%) setting controls how wide the ring is.
With Magnification API, the lens follows the cursor, so there is nothing to drag.

- Click inside the lens to close it and move the cursor to the point at the center of the lens.
- Double-click inside the lens to close it, move the cursor to that point, and double-click there.
With Magnification API, clicking the lens closes it.
Close the lens
Section titled “Close the lens”Press Escape or the activation shortcut. Escape is a fixed key; you can’t assign a different one, but you can turn off Escape to Exit in Settings.
