On my Mac, it is set up so that a square bracket is entered in MacOS and WindowsOS with Alt+5 or Alt+6. This has always worked, but since I started using OneNote in the Windows 11 virtual machine instead of OneNote for Windows 10, it no longer works there because the Alt+5 key combination is assigned differently there. This cannot be changed by entering it in the Parallels Desktop menu settings. Who can help: what other options do I have?
