A user just called me and reports they keep accidentally turning on the Windows 7 Screen Magnifier and they don't know how to turn it off. They also don't know how they are invoking it in the first place.
Since I don't use this feature I didn't know either. I wanted to share what I've now learned.
If you use the Windows Key + "The Plus Sign on the Keyboard" this will turn on the magnifier. As you keep pressing the Windows Key + "The Plus Sign on the Keyboard" it will keep increasing the magnification to wherever you have your cursor.
In order to turn it off you have to press Windows Key + Escape
This seems counter-intuitive to me. Seems like the Escape key by itself would have been the correct choice. The user still doesn't know how they are invoking it, but at least we know how to turn it off.
