ctrl + is a browser feature and not a babylon feature. We wonโt add those kind of hacks globally to the playground, but you can add it yourself:
> **[Disable or Prevent zooming(Ctrl+ or Ctrl-) in cross-browser | W3REIGN](https://w3reign.com/disable-or-prevent-zoomingctrl-or-ctrl-in-cross-browser/)**
>
> Disable or Prevent Browser zoom on , Ctrl+ or Ctrl-, and Ctrl + Mouse scroll. In my one of application I need to prevent the user, to zoom in and out over all cross browser. For a specific application I would like to disable or prevent the browser...

Itโs a bit out of scope of this forum, but if you want to show an example of code that partly works, please go right a head, we might be able to help!

just use event.preventDefault()
This works when canvas has focus;

use window.addEventlistener for entire page.
( **Note** ; In PG this will add a new eventListener every time you click run without disposing the old one!)

@Viche same method can be applied to wheel events,

You can completely disable the mouse wheel with ` camera.inputs.remove(camera.inputs.attached.mousewheel);`
If you still want the zoom in/out with the wheel but not with ctrl+wheel, I think you will have to track the ctrl key state in a keyboard handler and add a mouse handler where you disable the wheel action when the ctrl key is down.
