# navigation.wheelZoom

Part of [Navigation bar](https://kernstra.com/docs/web-sdk/config/navigation) in the Kernstra Web SDK 1.0.0 configuration reference.

- Type: `boolean`
- Default: `true`
- Page: https://kernstra.com/docs/web-sdk/config/navigation/wheelzoom

Trackpad pinch / Ctrl+wheel over the pages zooms the document, around the pointer, so what is under it stays put — instead of the browser zooming the whole page.
