I use Mac. When I do a presentation or make a screen recording, sometimes I need to zoom in to the part where the focus is; then I need to zoom out to restore the normal screen size.

I have seen people doing this, but I don't know how they achieved that by keyboard and mouse.

Does anyone know?

  • I know that we could post-process videos. But I have seen people doing this during presentation, so I think they achieved that in real-time by keyboard and mouse, that's what I want. – SoftTimur Nov 24 '20 at 3:53

I believe you can do this with accessibility features that are baked into macOS. They're located under System Preferences -> Accessibility. You can change the keyboard shortcuts under System Preferences -> Keyboard.

There are a couple different settings for the zoom type. It sounds like you might want to try fullscreen.


You can do that by holding the CTRL-key and scroll up (zoom in) or down (zoom out).

You may have to enable the setting first. The setting is called "Use scroll gesture with modifier keys to zoom:". You can find it under System Settings -> Accessibility -> Zoom.

Make sure Zoom style is set to Full screen.


Assuming you have pinch to zoom enabled in your trackpad settings, couldn't you pinch in and out on the trackpad in order to zoom in and out?
