Can you assign a different shortcut?
Microsoft’s Magnifier instructions document Ctrl+Alt+Minus for the zoom toggle, but do not explain how to reassign it. They also do not establish a built-in Windows setting for changing that assignment. If you need a different key combination, these instructions do not provide a supported remapping method; changing the zoom level or increment in Magnifier settings is the documented alternative.
