Hi Charlene Dobell,
Thank you for your question. Based on the current Windows accessibility options, Magnifier does not include a built-in feature that automatically magnifies content when you click or hover over an area with the mouse.
The closest available option is to have Magnifier follow your mouse pointer as you move around the screen. As I have checked and validated, AI answer has provided the correct steps for you to follow.
If you need easier one-handed operation, you may want to explore a dedicated accessibility or screen magnification application that offers hover-based zoom controls, as this type of functionality is not currently available in the standard Windows Magnifier feature set.
You can also share your accessibility requirements through the Windows Feedback Hub (Windows + F), as real-world accessibility scenarios help inform future product improvements.

I hope this helps clarify what is currently available.
