Zoom in where the focus is 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 believe you can do this with accessibility features that are baked into macOS. They're located under System Preferences -&gt; Accessibility. You can change the keyboard shortcuts under System Preferences -&gt; Keyboard.
There are a couple different settings for the zoom type. It sounds like you might want to try fullscreen.
