The suggested corrections in the InDesign spell checker are so small I can hardly see them. Is there anyway to make that text larger?
On Mac, in System Preferences > Universal Access > Seeing, you can enable zoom and use it with keyboard shortcuts, and/or keypad gestures. I can't remember where to find and set the keypad info. On my MacBook Pro, holding Cmd and dragging two fingers up on the trackpad zooms in, and dragging two finders down zooms out. Search Google for terms like "mac keypad zoom gesture" without quotes, if you want more detail.
On Windows, search Google for terms like "free Windows screen magnifier" without quotes, for suggestions. I used one or another of them when I worked on a PC.
